OPINION
FERGUSON, Senior Circuit Judge.
This appeal presents the issue of whether a temporary detention ordered by the California Youth Authority Youth Offender Parole Board may be treated as either a prior sentence or a constructive parole revocation for the purpose of calculating criminal history points under the Sentencing Guidelines (“Guidelines”). Appellee Giovanni Ramirez pleaded guilty to a Class A felony with a statutory minimum sentence of 10 years. The District Court found that Ramirez’s two prior temporary detentions, which were ordered by the Youth Offender Parole Board as a result of [796]*796alleged parole violations, were neither pri- or sentences under U.S. Sentencing Guidelines Manual § 4Al.l(c) (2002) [hereinafter U.S.S.G.], nor terms of imprisonment imposed as a result of a revocation of parole that could be aggregated with Ramirez’s juvenile sentence under U.S.S.G. § 4A1.2(k) (2002). As a result, the District Court determined that Ramirez had no criminal history points and was eligible for a “safety-valve” departure from the mandatory minimum under U.S.S.G. § 5C1.2 (2002).
We have jurisdiction pursuant to 18 U.S.C. § 3742(b) (2002) and 28 U.S.C. § 1291 (2002). Because we conclude that the temporary detentions neither resulted from “adjudications of guilt” beyond a reasonable doubt nor constituted returns to the original term of imprisonment such that they could be treated as constructive revocations of parole, we affirm.
I. BACKGROUND
On December 19, 2000, Ramirez pleaded guilty to distribution of 62.5 grams of methamphetamine, a Class A felony carrying a statutory minimum sentence of 10 years. 21 U.S.C. § 841(b) (2002). Based on Ramirez’s record with the California Youth Authority (CYA), discussed below, the Probation Department’s Presentence Report (PSR) concluded that Ramirez had two criminal history points and was therefore ineligible for a safety-valve departure from the mandatory minimum.
A. Ramirez’s History with CYA
On September 27, 1989, at the age of seventeen and over ten years before the instant offense, Ramirez was found guilty of rape and four other counts and placed in the custody of CYA. Ramirez served a little less than four years of his fourteen year sentence and was paroled from CYA on July 29, 1993, over five years prior to the commission of the instant offense.
On June 21, 1996, Ramirez was issued a citation for speeding. Three days after the citation, he tested positive for marijuana use. As a result of these two occurrences, his parole officer prepared a Corrective Action Plan (CAP)1 which recommended that Ramirez receive 30 days of “temporary detention” at Los Angeles County Jail.2 On July 24, Ramirez signed the CAP and checked a box indicating that he admitted to the speeding and marijuana allegations, waived all rights to a fact-finding hearing, and accepted the recommended CAP. On August 2, 1996, the Youth Offender Parole Board (YOPB) concurred with the CAP and ordered the temporary detention. The YOPB order did not indicate that there had been either a probable cause or a violation determination. Ramirez was detained from July 24 through August 19,1996.
On November 18, 1996, Ramirez was arrested for possession of a concealed weapon. He was subsequently detained pending a determination of whether the arrest constituted a violation of his parole. On November 20, 1996, Ramirez waived his right to a probable cause hearing, and on November 27, 1996, YOPB issued an order making a probable cause finding as [797]*797to the alleged violation. On January 8, 1997, Ramirez’s parole officer issued a disposition report recommending that Ramirez be continued on parole and placed in a drug treatment program.
On April 11, 1997, the YOPB issued an order requiring that Ramirez continue to be detained pending a hearing on his alleged violation. The order stated that Ramirez “had several violations in 1996 and his commitment offense, recent parole performance, and this arrest necessitate a violation]/ disposition hearing.” On May 1, 1997, Ramirez signed a form acknowledging that he had received notice of his rights regarding the parole hearing and waiving his right to a fact-finding hearing, witnesses, or the assistance of an attorney. He admitted the weapons possession allegation as described in the probation disposition report.
On May 13, 1997, based on Ramirez’s admission, the YOPB found that there had been a parole violation. However, instead of revoking his parole, the YOPB ordered Ramirez to spend two weeks in temporary detention. The order specifically noted under “Reasons” for its disposition that Ramirez would “be better served by parole supervision.” Ramirez was released from temporary detention on May 27, 1997. It is undisputed by the parties that Ramirez’s parole was never actually revoked under state law. On September 11, 1997, Ramirez was discharged from CYA parole.
B. Sentencing for the Instant Offense
The District Court conducted a total of eight sentencing hearings. In addition to their initial sentencing briefs, the parties submitted three sets of supplemental briefs, and the probation office submitted two addenda to the PSR. In addition, the District Court requested and heard testimony from both of Ramirez’s CYA parole officers and from the YOPB member who had signed the two temporary detention orders.
On December 7, 2001, the District Court issued its sentencing decision.3 Specifically, the District Court found that (1) Ramirez’s parole was not “revo[ked]” as that term is used in U.S.S.G. § 4A1.2(k); (2) Ramirez’s temporary detentions were not the result of an “adjudication of guilt” and therefore could not be treated as prior sentences under U.S.S.G. § 4A1.2(d)(2)(B); and (3) in light of the above findings, Ramirez was eligible for a safety-valve departure under U.S.S.G. § 5C1.2. On January 2, 2002, the government filed its notice of appeal.
II. STANDARD OF REVIEW
A district court’s interpretation of the Sentencing Guidelines is reviewed de novo. See United States v. Veerapol, 312 F.3d 1128, 1131 (9th Cir.2002). Factual findings underlying a district court’s sentencing determination are reviewed for clear error. See id. at 1131-32. “The government bears the burden of proving the fact of a prior conviction.” United States v. Sanders, 41 F.3d 480, 486 (9th Cir.1994). Whether “a prior adjudication falls within the scope of the Sentencing Guidelines” is a question of law that is reviewed de novo. Id. at 486; see also United States v. Latimer, 991 F.2d 1509, 1511 (9th Cir.1993).
III. DISCUSSION
The government contends that the District Court erred in finding that Ramirez [798]*798was eligible for a safety-valve departure because Ramirez should have had at least two points added to his criminal history score as a result of his two YOPB imposed temporary detentions, either because the detentions are “prior sentences” under U.S.S.G. § 4A1.1 or because the detentions constituted constructive parole revocations that, under U.S.S.G. § 4A1.2(k), could be aggregated with Ramirez’ juvenile sentence of imprisonment.4
A. Temporary Detention as a Prior Sentence under U.S.S.G. § 4Al.l(c)
Under U.S.S.G. § 4A1.1(c), a defendant receives one criminal history point for “each prior sentence[that is neither a prior sentence of imprisonment exceeding one year and one month] or [a prior sentence of imprisonment of at least sixty days], up to a total of 4 points.” U.S.S.G. § 4A1.1(c). The definition of a “prior sentence” is “any sentence previously imposed upon an adjudication of guilt, whether by guilty plea, trial, or plea of nolo contende-re, for conduct not part of the instant offense.” § 4A1.2(a)(1).
The District Court determined, and Ramirez urges on appeal, that the proceedings underlying the temporary detentions were not “adjudications of guilt.” “When interpreting the sentencing guidelines, we have carefully distinguished between confinement resulting from an adjudication of guilt and confinement for other reasons.” United States v. Johnson, 205 F.3d 1197, 1200 (9th Cir.2000). “Absent proof that the [prior] court found [the defendant] guilty beyond a reasonable doubt, [an] adjudication may not be used to increase [the] criminal history score.” Sanders, 41 F.3d at 486.
In the instant case, the government has failed to show that either of the detentions resulted from a finding of guilt beyond a reasonable doubt. The regulation authorizing the YOPB to order a temporary detention requires only a preponderance showing. Cal. Code Regs. tit. 15 § 4985(c)(6).5 Because neither of the detentions were imposed as a result of, nor even required, a finding of guilt beyond a reasonable doubt, we agree with the District Court that neither can be viewed as “prior sentences” for the purpose of increasing Ramirez’s criminal history score.
The government asserts that because Ramirez admitted to the allegations in both cases, there is no need to show that there was a finding of guilt. However, the Guidelines specifically require that an “adjudication of guilt” result from a “guilty plea, trial, or plea of nolo contendere.” U.S.S.G. § 4A1.2(a). No mention is made of “confessions” or “admissions.” “A plea of guilty is more than a confession which admits that the accused did various acts; it is itself a conviction.” Boykin v. Alabama, 395 U.S. 238, 242, 89 S.Ct. 1709, 23 [799]*799L.Ed.2d 274 (1969). As such, a valid plea requires that “an accused facing ... imprisonment [receive] the utmost solicitude of which courts are capable in canvassing the matter with the accused to make sure he has a full understanding of what the plea connotes and of its consequence.” Id. at 243-44, 89 S.Ct. 1709; cf. Fed. R. Crim. P. 11(b) (setting out requirements for a valid plea allocution). The government has presented no evidence that Ramirez’s admissions were the functional equivalent of a valid plea. Cf. United States v. DiPina, 230 F.3d 477, 484-85 (1st Cir.2000) (describing factors required for finding of constructive plea). The fact that Ramirez admitted to the allegations, without more, is not sufficient to transform the proceedings into a prior adjudication of guilt under § 4A1.2(a).
B. Temporary Detention as a Constructive Revocation of Parole
The government. alternatively asserts that the District Court erred because the temporary detentions should have been treated as constructive revocations of parole and aggregated with Ramirez’s prior sentence. Specifically, the government argues that the term “revocation,” as used in U.S.S.G. § 4A1.2(k), should be interpreted to include any, instance in which confinement is imposed due to a parole violation, even where parole is not formally revoked under state law.
The Guidelines require that revocations of parole be considered in calculating a sentence so that “the original term of imprisonment [is added] to any term of imprisonment imposed upon revocation.” U.S.S.G. § 4A1.2(k)(l), “To qualify as a sentence of imprisonment, the defendant must have actually served a period of imprisonment on such sentence.” U.S.S.G. § 4A1.2 cmt. n. 2. In addition,
[Revocation of ... parole ... may affect the time period under which certain sentences are counted as provided in § 4A1.2(d)(2) and (e). For the purposes of determining the applicable time period, use the following: ... (ii) in the case of any other confinement sentence for an offense committed prior to the defendant’s eighteenth birthday, the date of the defendant’s last release from confinement on such sentence (see § 4A1.2(d)(2)(A)).
U.S.S.G. § 4A1.2(k)(2)(B).
In determining the meaning of “revocation” under the Guidelines, we must apply a uniform, federal definition, “not dependent upon the vagaries of state law.” See United States v. Martinez, 232 F.3d 728, 732 (9th Cir.2000) (citing Taylor v. United States, 495 U.S. 575, 591-92, 110 S.Ct. 2143, 109 L.Ed.2d 607 (1990)). Thus, to the extent the District Court relied exclusively on state law definitions of “revocation,” it erred. However, because we determine that under a federal definition of revocation, Ramirez’s parole was not revoked in either instance, such error by the District Court was harmless.
1. Definition of Revocation Under - § 4A1.2(k)
The purpose of creating a uniform federal definition of terms within the Guidelines is to effectuate consistent nationwide application of federal legislation. See Taylor, 495 U.S. at 591, 110 S.Ct. 2143 (quoting Dickerson v. New Banner Institute, Inc., 460 U.S. 103, 119-20, 103 S.Ct. 986, 74 L.Ed.2d 845 (1983)). In determining what the federal 'definition of a particular term is, courts look to the plain language and legislative history of the statute, as well as the use of the term in practice. See Taylor, 495 U.S. at 594-98, 110 S.Ct. 2143. As with all penal statutes, the rule of lenity requires that we construe ambig[800]*800uous terms in favor of the accused. Id. at 596, 110 S.Ct. 2143. “This maxim of statutory construction, however, cannot dictate an implausible interpretation of a statute, nor one at odds with the generally accepted contemporary meaning of a term.” Id. (citing Perrin v. United States, 444 U.S. 37, 49 n. 13, 100 S.Ct. 311, 62 L.Ed.2d 199 (1979)).
In contrast to criminal offenses, the elements of which frequently vary from state to state, the definition of “revocation” is consistent from state to state. Like the terms “conviction” or “plea,” the term “revocation” describes a specific outcome of a process, the basic requirements of which have been clearly articulated by the Supreme Court. We look to these constitutional requirements to determine the outer boundaries for the federal definition of revocation before proceeding to consider the statutory text and contemporary understanding of the term.
a. Constitutional Requirements for Probation or Parole Revocation
Before a revocation of parole or probation can occur, the Constitution requires that there be (1) a formal finding that a probationer or parolee has committed a violation and (2) a determination that the violation was serious enough to warrant reimposing the probationer’s or parolee’s original sentence. See Morrissey v. Brewer, 408 U.S. 471, 479-80, 92 S.Ct. 2593, 33 L.Ed.2d 484 (1972) (setting out requirements for parole revocation); see also Gagnon v. Scarpelli, 411 U.S. 778, 93 S.Ct. 1756, 36 L.Ed.2d 656 (1973) (extending requirements of Morrissey to probation revocation hearings). Because the consequences of the revocation process are serious, see Morrissey, 408 U.S. at 482, 92 S.Ct. 2593, the probationer or parolee must be afforded an opportunity to present evidence to suggest that his violation does not warrant revocation. See id. at 487-88, 92 S.Ct. 2593. In addition to a preliminary hearing to determine whether there was reasonable cause to believe that a probationer or parolee had violated the conditions of his probation or parole, a final revocation hearing must be held by the probation or parole authority, if so desired by the probationer or parolee, in order to determine whether revocation is actually warranted. See id. at 486-88, 92 S.Ct. 2593.
A violation alone does not automatically trigger a revocation. See id. at 479, 92 S.Ct. 2593. Probation or parole authorities generally have two options: modify or extend the conditions of supervision, or revoke. See, e.g., U.S.S.G. § 7B1.3(a)(2) (2002). Where other steps are available which will protect society and improve chances of rehabilitation, revocation is generally inappropriate. See Morrissey, 408 U.S at 480, 92 S.Ct. 2593, see also id. at 484, 92 S.Ct. 2593 (“Society ... has an interest in not having parole revoked because of erroneous information or because of an erroneous evaluation of the need to revoke parole, given the breach of parole conditions.”). The probation or parole authority, having both expertise and the entire record of the probationer or parolee before it, is presumptively the party in the best position to choose whether to revoke or impose some form of intermediate sanction. See id. at 480, 92 S.Ct. 2593 (“deciding what to do about the violation once it is identified ... is not purely factual but also predictive and discretionary”).
In sum, before a district court can conclude that there has been a revocation pursuant to § 4A1.2(k), there must be, at minimum, a showing that the requirements of Morrissey were met. See Johnson, 205 F.3d at 1199-1200 (finding record insufficient to uphold finding of revocation [801]*801where probationer was detained three times and no revocation hearing was ever held). Where a parole or probation authority has effectuated an actual revocation, the government can rely on the record from that proceeding to show that § 4A1.2(k) is applicable. See United States v. Newman, 912 F.2d 1119, 1122 (9th Cir.1990) (where government has presented record of prior conviction, defendant may rebut government’s assertion that prior conviction occurred by showing constitutional invalidity of proceeding). However, where no such record is present, we must presume that no revocation occurred.
b. Ordinary Meaning & Legislative History
Keeping in mind the requirements of Morrissey, and following the two general principles that (1) “[c]ourts can and should ... adopt statutory interpretations, when feasible, that will avoid serious constitutional issues,” United States v. Hernandez, 322 F.3d 592, 602 (9th Cir.2003) (as amended), and (2) “penal statutes must be strictly construed,” Gasho v. United States, 39 F.3d 1420, 1432 n. 11 (9th Cir.1994) (citing United States v. Wiltberger, 5 Wheat. 76, 18 U.S. 76, 95, 5 L.Ed. 37 (1820)), we now turn to the language in the Guidelines discussing revocation.
The particular provision at issue here requires that “the original term of imprisonment [be added] to any term of imprisonment imposed upon revocation.” U.S.S.G. § 4A1.2(k)(l). Neither the Guidelines nor Commentary to the provision provides a definition of revocation. However, the “conventional understanding of ‘revoke’ [is] ‘to annul by recalling or taking back.’ ” Johnson v. United States, 529 U.S. 694, 704, 120 S.Ct. 1795, 146 L.Ed.2d 727 (2000) (quoting WebsteR’s Third New Int’l Dictionary 1944 (1981)). Under this definition, revocation occurs when the privilege of remaining under parole or probation supervision, as opposed to imprisonment, is annulled or cancelled. Modifications of the terms of parole or probation, under which the parolee or probationer remains under the supervision of probation, are not covered, as parole or probation supervision continues and is therefore not “annulled.”6
This construction is consistent with the Guidelines’ own probation scheme, which gives sentencing courts discretion to “revoke ... or [ ] extend the term of probation or supervised release and/or modify the conditions of supervision.” U.S.S.G. § 7B1.3(a)(2) (emphasis added). By articulating a clear distinction between formal revocation proceedings and modifications imposed as a result of lower-level violations, the Guidelines contemplate the serious nature of revocation and distinguish it from lesser sanctions imposed without the full protections Morrissey requires. Where the terms of probation are modified, including imposition of temporary periods of confinement, but the probationer remains under the supervision of the probation entity, revocation has not occurred. But see United States v. Glover, 154 F.3d 1291, 1293-94 (11th Cir.1998) [802]*802(discussed infra) (rejecting defendant’s argument that modifications cannot be treated as revocations under the Guidelines).7 Thus, the term “revocation,” as used in § 4A1.2(k)(l), requires that before probation or parole supervision can continue after a revocation, the sentencing authority must sentence the defendant anew.
The rule of lenity favors such a narrow construction. We “will not interpret a federal criminal statute so as to increase the penalty that it places on an individual when such an interpretation can be based on no more than a guess as to what Congress intended.” Latimer, 991 F.2d at 1514 (quoting Bifulco v. United States, 447 U.S. 381, 387, 100 S.Ct. 2247, 65 L.Ed.2d 205 (1980)) (citation omitted). In this case, the government has presented no evidence that Congress intended any violation accompanied by a confinement sanction to be treated as a revocation for the purposes of § 4A1.2(k). As discussed above, we believe that the plain language suggests the contrary. Given that neither the text nor the commentary contemplate such an interpretation, and given the constitutional concerns raised by subsequently recategorizing informal modification procedures as implicitly compliant with the requirements of Morrissey, we must construe the statute narrowly.
Finally, we note that this construction of § 4A1.2(k) does not preclude the use of evidence of parole or probation conduct that the government believes is relevant to sentencing, nor does it undermine the general premise that “repeated criminal behavior is an indicator of a limited likelihood of successful rehabilitation.” U.S.S.G. ch. 4, pt. A., introductory cmt. (2001); contra Glover, 154 F.3d at 1294 (quoting Glidden, 77 F.3d at 40) (indicating that failing to treat probation violations as revocations under § 4A1.2(k) would be contrary to the purpose of the Guidelines). The government is still free to present to the court “reliable information ... [that] indicates that the criminal history category does not adequately reflect ... the likelihood that the defendant will commit other crimes.” U.S.S.G. § 4A1.3.
The government nevertheless argues that any term of confinement presumptively reflects an intent to annul the privilege of parole or probation, regardless of whether the parole or probation entity expresses such an intent in a formal determination. Essentially, the government is arguing that a narrow construction is “at odds with the generally accepted contemporary meaning” of revocation. Taylor, 495 U.S. at 596, 110 S.Ct. 2143 (citing Perrin, 444 U.S. at 49 n. 13, 100 S.Ct. 311). We agree that any uniform federal definition should comport with state and federal probation practice. Interpretation of the Guidelines “can be informed by how the states interpret and apply their own criminal laws.” United States v. Wood, 52 F.3d 272, 276 n. 4 (9th Cir.1995). We therefore turn to practice in order to address whether the government’s suggested presumption is warranted.
c. State and Federal Practice
It is clear that, in practice, the imposition of a term of confinement during the ordinary course of parole or probation does not necessarily mean that a revocation has occurred. State statutes describe a wide array of intermediate sanctions [803]*803which are clearly intended as alternatives to revocation; some, like the statute in this case, are uniquely targeted at juvenile parolees or probationers.8 The most commonly available sanctions are modifications such as increased supervision, lengthened terms of parole, or enrollment in so-called “boot camp” or “scared straight” programs. See supra note 8. Temporary detention statutes like the one utilized in the instant case are also common. See id.
From this vast array of options, parole or probation officials choose the punishment that they believe will best address the needs of the individual parolee or probationer. A finding of a “technical” or lower-level violation typically results in the imposition of an intermediary sanction and not in actual revocation. See generally U.S. Probation Office, Cent. Dist. of Cal. Revocation WoRkbook (last revised 2003). Because their primary aim is to act as a warning to the parolee or probationer, modification procedures generally lack the formality or due process protections required by actual revocation; they are not [804]*804intended to rise to the level of a formal revocation.9
It is clear that a violation can result in a vast range of sanctions, including revocation, none of which are necessarily directly related to either the seriousness of the violation or the culpability of the parolee or probationer. Cf. U.S.S.G. § 7B1.3(a) (distinguishing between mandatory versus discretionary revocation on the basis of the seriousness of the violation). The inherently flexible and discretionary nature of the different state systems, which aim to consider the totality of the parolee’s or probationer’s history as well as the gravity of the violation, leads to discrepancies in the type of sanctions handed down for even the same minor violations. A definition of revocation that looks only to the nature of the sanction imposed would thus result in a rule that is more arbitrary than what would result if we adhered to an actual revocation requirement. Parolees or probationers who engaged in similar offenses would receive vastly different sentences based on unsubstantiated guesses as to what parole or probation boards intended to do. We do not believe that Congress contemplated such a result when it wrote § 4A1.2(k).
In short, both Morrissey and practice instruct that we should defer to the original parole or probation entity to determine whether or not revocation is an appropriate sanction for the violation. By engaging in ad-hoc determinations that violations are of a sufficiently serious nature to warrant revocation, or by interpreting a particular sanction as indicative of an intent to revoke, subsequent courts usurp the discretion of the parole or probation authority. Where the parole or probation authority followed the procedures required for revocation but explicitly chose not to initiate revocation, we cannot second-guess that determination any more than we could determine that a defendant who was punished as severely as they would have been for murder was “constructively” convicted of murder.
2. Other Circuits’ Treatment of § 4A1.2(k)
We recognize that our narrow construction of § 4A1.2(k) potentially conflicts with the holdings of other circuits addressing this question. See Glover, 154 F.3d at 1294-95 (holding that “ § 4A1.2(k) contemplates that, in calculating a defendant’s ... sentence ..., the district court will aggregate any term of imprisonment imposed because of a probation violation”); United States v. Reed, 94 F.3d 341 (7th Cir.1996) (embracing Glidden); Glidden, 77 F.3d at 40 (holding that when a probationer is found to have - “violated probation [and in response has been] ordered ... to serve a period of incarceration, we think it proper to view that order as at least a partial revocation ... within the scope of ... § 4A1.2(k)(1).”).
As an initial matter, we note that only one of the other circuits considering the question has dealt specifically with the modification versus actual revocation distinction. See Glover, 154 F.3d at 1294-95. In the other two cases, the probationer was resentenced to probation after the period of incarceration, see Reed, 94 F.3d at 342-43; Glidden, 77 F.3d at 39. Thus the other decisions were more closely in accord with the commonly understood meaning of revocation. In addition, none of the other cases dealt with a statute such as the temporary detention statute in this case, which explicitly creates a diversionary disposition only applicable to juveniles. See generally, U.S.S.G. § 4A1.2(f) (juvenile di[805]*805versionary dispositions not counted as sentences under the Guidelines).
More importantly, none of these cases consider, either explicitly or implicitly, the constitutional requirements for revocation set out in Morrissey. Nor did any of the courts have the benefit of the usual definition of revocation articulated by the Supreme Court in Johnson v. United States.10 The only rationale provided for their holdings is the general commentary introducing the Criminal History chapter of the Guidelines. See Glover, 154 F.3d at 1294; Glidden, 77 F.3d at 40. As discussed above, we believe that the availability of § 4A1.3 adequately addresses the concern that the failure to consider such violations will result in inadequate criminal history scores.
To the extent they are inconsistent with this opinion, we find the decisions in the other circuits treating any violation followed by confinement as a revocation of parole under § 4A1.2(k) to be unpersuasive. To the extent they presume that constructive revocations exist, the holdings ignore the plain language of § 4A1.2(k) and the general rule that we construe penal statutes strictly. They also fail to consider the constitutional requirements for revocation set out in Morrissey. Finally, the other circuits’ approach does not grant sufficient deference to the reasoned determinations of parole or probation authorities, who are in a better position than subsequent courts to determine whether a particular violation is sufficiently grave to warrant revocation.
3. Ramirez’s Parole Was Not Revoked Under Federal Law
In the instant case, neither temporary detention can be equated with a revocation of parole that could be aggregated with Ramirez’s juvenile sentence under § 4A1.2(k). Indeed, both detentions were clearly ordered as alternatives to revoking Ramirez’s parole.
With regard to the first violation, there has been no showing that the requirements of Morrissey were met. See Johnson, 205 F.3d at 1199-1200 (finding record insufficient to uphold finding of revocation where probationer was detained three times and no revocation hearing was ever held). There was neither a probable cause hearing nor a violation finding.11
With regard to the second temporary detention, the parole authority neither made a finding of revocation nor returned Ramirez to parole subsequent to his detention. In fact, the YOPB explicitly found that no revocation was necessary and stated that Ramirez would be better served by remaining under the supervision of parole officials. The temporary detention is thus more accurately viewed as a modification of the terms of Ramirez’s parole, as opposed to a revocation. In light of the usual meaning of the term revocation, and state and federal practice, we hold that the second temporary detention does not fall within the scope of § 4A1.2(k).
In sum, we find that Ramirez’s parole was never actually revoked, nor can his time in temporary detention be equated with imprisonment, as he remained under parole supervision. We therefore hold that the District Court did not err in determining that neither of the two temporary detentions ordered by YOPB consti[806]*806tuted a constructive revocation of parole under § 4A1.2(k).
IY. CONCLUSION
For the reasons discussed above, we hold that the District Court did not err in determining that neither of the two temporary detentions ordered by YOPB constituted either a prior sentence under § 4Al.l(c) or a constructive revocation of parole under § 4A1.2(k).
The judgment of the District Court is AFFIRMED.
