Opinion for the court filed PER CURIAM.
The Sentencing Guideline commonly known as the “safety valve” limits the applicability of statutory minimum sentences in certain cases. U.S. Sentencing Guidelines Manual § 5C1.2 (1995) [hereinafter U.S.S.G.]. A defendant who qualifies for the safety valve also receives a two-level reduction in offense level under U.S.S.G. § 2D1.1(b)(4). To qualify, a defendant must overcome five hurdles, one of which is that the defendant must not have “possessed] a firearm ... in connection with the offense.” Id. § 5C1.2(2). Application Note 3 to the safety valve defines the word “offense” to mean “the offense of conviction and all relevant conduct.” Id. application note 3. Appellant Hugh O. Plunkett appeals his conviction on the principal ground that the district court erred as a matter of law in using this broad definition of “offense” to deny him the two-level reduction under U.S.S.G. § 2Dl.l(b)(4). We affirm.
I.
Following his indictment on six narcoties- and weapons-related counts, Plunkett pled guilty to one count of possession with intent to distribute more than 50 grams of crack, a form of cocaine base. See 21 U.S.C. § 841(a)(1), (b)(l)(A)(iii) (1988 & Supp. V 1993). Under the terms of the plea agreement, his plea related only to the drugs found on his person when he was arrested, and not to more than 500 grams of crack and a firearm found the next day in his apartment. For sentencing purposes, however, Plunkett acknowledged as part of his plea agreement his responsibility for the additional crack and the firearm.
The district court sentenced Plunkett to 189 months imprisonment. Starting from a base offense level of 36, see U.S.S.G. § 2Dl.l(c)(2), the court imposed a two-level increase for possession of a firearm under U.S.S.G. § 2D1.1(b)(1) and a three-level reduction for acceptance of responsibility under U.S.S.G. § 3El.l(a), resulting in an offense level of 35. The court found that Plunkett could not qualify for the safety valve because, under Application Note 3, his firearm possession was part of the offense as “relevant conduct”; thus, the court could not apply the two-level reduction under U.S.S.G. § 2Dl.l(b)(4). Because Plunkett had no pri- or criminal record, the sentencing range was between 168 and 210 months, and the court chose a sentence at the midpoint of that range.
II.
On appeal, Plunkett contends that the provision in the safety valve barring eligibility as a result of firearm possession “in connection with the offense” depends only on the offense of conviction — here, a conviction based solely on the drugs found on his person at the time of his arrest — and not, as the government maintains, the offense of conviction and all relevant conduct — here, the greater drug distribution scheme, including the crack found at his apartment. Specifically, he contends that the district court erred as a matter of law in applying Application Note 3 because it is inconsistent with both the safety valve and the provision in the Guidelines entitled “Relevant Conduct,” U.S.S.G. § 1B1.3. Because these arguments were not presented to the district court, our review is for plain error,

v. Robinson,
First, we are unpersuaded that Application Note 3’s interpretation of the safety valve is invalid because it purportedly negates any difference between the word “offense,” used in three subsections of the safety valve, U.S.S.G. § 5C1.2(2)-(4), and the phrase “the offense or offenses that were part of the same course of conduct or of a common scheme or plan,” used in another subsection, U.S.S.G. § 5C1.2(5). Even if Application Note 3 is viewed, in this respect, as somewhat odd, “[c]ommentary is not ‘inconsistent’ with a guideline simply because it adopts what [this court] might regard as one of the less likely interpretations of a guideline.”
Robinson,
Further, there is no inconsistency, much less the “flat inconsistency” necessary to invalidate commentary,
Stinson v. United States,
Moreover, while implicit cross-referencing is disfavored in light of the norm of explicit cross-referencing in the Guidelines,
see United States v. Chatman,
Finally, the district court did not plainly err in finding that the safety valve did not apply to Plunkett, although we need not resolve the relationship between the standard for the safety valve and the standard that governs the two-level enhancement for weapon possession under U.S.S.G. § 2Dl.l(b)(l). The commentary to the enhancement provision instructs that the two-level upward “adjustment should be applied if the weapon was present, unless it is clearly improbable that the weapon was connected with the offense.” U.S.S.G. § 2D1.1 application note 3. Plunkett maintains that the “clearly improbable” standard has no relevance to the safety valve’s reference to use or possession of a firearm “in connection with the offense” and notes that this court has distinguished between weapons possession under the enhancement guideline and the safety valve.
See In re Sealed Case (Sentencing Guidelines’ “Safety Valve”),
Accordingly, we affirm the judgment of conviction.
Notes
. We acknowledge that both counsel discussed the scope of the "offense” under the safety valve at some length with the district court, but we fail to find any reference to the particular arguments *875 advanced on appeal. Indeed, defense counsel appeared not to contest that the offense for purposes of the safety valve included the entire drug distribution scheme, not just the offense of conviction. We cannot agree with Plunkett that on appeal he has simply “provided additional detail in support of his argument” or that "his arguments at sentencing and on appeal are one and the same.”
. We reject the government’s suggestion that, under the language of
Stinson,
challenges to guideline commentary based on inconsistency with a guideline are allowed only when the commentary is inconsistent with the particular guideline it interprets.
See Stinson,
. In addition, the broader definition of "offense” in Application Note 3 is consistent with congressional intent in enacting the safety valve. Congress meant the safety valve to prevent the situation in which the "least culpable offenders may receive the same sentences as their relatively more culpable counterparts.” H.R. Rep. No. 103-460, at 4 (1994). If other relevant conduct has bearing upon the offender’s culpability, the district court appropriately considers such conduct in applying the safety valve. Given this intent it would be odd if eligibility for sentencing under the safety valve precluded consideration of relevant conduct.

. We need not address Plunkett’s contention that the government should bear the burden of proof to demonstrate a defendant’s ineligibility for the safety valve, for prevailing on this issue would not change the disposition of his appeal.
. In light of our disposition we do not address whether imposition of a two-level enhancement for when "a dangerous weapon ... was possessed” under U.S.S.G. § 2D1.1(b)(1) should preclude application of a two-level decrease under the safety valve and U.S.S.G. § 2D1.1(b)(4) as a matter of law. We note, however, that the government concedes, in light of
