Between October 1992 and September 1994, Anthony Thomas sent five death threats to Carol Evans Walker, an Illinois Assistant State’s Attorney who successfully prosecuted him for armed robbery. Thomas was eventually charged with and convicted of two counts of mailing threatening communications, in violation of 18 U.S.C. § 876. The district judge sentenced Thomas to 60 months on each count, to be served consecutively after Thomas’ release from the Illinois Department of Corrections (IDOC). The district judge also sentenced Thomas to three years of supervised release and a $100 special assessment. On appeal, Thomas challenges the admission of certain evidence, the imposition of a six-level increase in his base offense level pursuant to United States Sentencing Guideline (U.S.S.G.) § 2A6.1(b)(l) and the refusal to group his counts under U.S.S.G. § 3D1.2. We affirm Thomas’ conviction, but remand for reconsideration of his sentence.
I. Testimony of Jack Rivera
Jack Rivera, an IDOC correction counselor, testified at trial about a disciplinary hearing that was held to determine whether Thomas was responsible for the letter sent to Walker in October 1992. This same letter formed the basis of Count 1 of the indictment. On direct examination, Rivera read a paragraph of the summary he prepared after the IDOC hearing:
Records of proceedings. Report read. [Anthony Thomas] admits he told investigator that he allowed his .brother ... to use [Anthony Thomas’] name and [prisoner] number on a letter that his brother wrote. [Anthony Thomas] admits he made admission to investigator “if he saw Carol Evans Walker on the street, he would catch a battery case on her” but states he was referring to his brother’s feelings. [Anthony Thomas] states Carol Walker prosecuted his brother not him.
Tr. 52-53. On cross, the defense emphasized that Thomas had denied writing the letter:
Defense: Officer Rivera, based on the fact that your report says that Anthony Thomas told you someone else wrote the letter, Anthony Thomas denied writing the letter?
Rivera: You could draw that conclusion.
Defense: Now, Anthony Thomas does have brothers, correct?
Rivera: I don’t know.
Defense: You didn’t feel that was important to even find out?
Rivera: At this — today, I don’t know what his family status is.
Tr. 55. On redirect, the government clarified that the IDOC was interested in whether Thomas was the mastermind behind the letter, not whether Thomas had actually put pen to paper and written the letter himself:
Gov’t: Based on what you have in your report, in the summary, you were interested in determining whether the Defendant was responsible for sending this threatening letter, not who wrote it; is that a fair statement?
Rivera: Correct.
Gov’t: And you determined that Defendant was responsible for this threatening letter?
Defense: Your Honor, I object to what the conclusions were drawn by a disciplinary panel at the Department of Corrections.
Court: No, if it has to do with this matter, I think it’s relevant. I’ll allow it. Overruled.
Rivera: Could you repeat the question please?
Gov’t: Sure. Did you determine that the Defendant was responsible for mailing a threatening communication to Carol Walker?
Rivera: Correct.
Tr. 56-57. On appeal, Thomas argues that the jury may have reasoned that because the IDOC determined that Thomas was responsible for the October 1992 letter, he was guilty of the crimes charged in the indictment. Therefore, Thomas asserts, the probative value of Rivera’s testimony was substantially
*836
outweighed by the danger of unfair prejudice, and the district court should have excluded Rivera’s testimony pursuant to Federal Rule of Evidence 403. Although we afford a significant amount of deference to a district court’s Rule 403 determination,
see United States v. Smith,
Unsurprisingly, the government does not argue that Rivera’s statement is the sort of evidence that is ordinarily admissible. The probative value of the testimony was limited at best, since the sole purpose of the hearing was to determine whether Thomas should be disciplined under IDOC policies, not whether Thomas had violated federal criminal law.
Cf. United States v. Hanahan,
The government relies on the principle that if a party opens the door to evidence that would ordinarily be inadmissible, he cannot complain about the admission of the evidence on appeal.
See United States v. Moore, 115 F.3d
1348, 1358
(7th
Cir.1997);
United States v. Wynn,
Thomas is not entitled to a new trial, however, because the error was harmless.

*837 II. Sentencing
The district court increased Thomas’ base offense level pursuant to U.S.S.G. § 2A6.1(b)(l), which mandates a six-level increase “[i]f the offense involved any conduct evidencing an intent to carry out” the threat. The district court explained:
In the instant case, the Court finds that the § 2A6.1 enhancement is valid. Defendant’s letters to Carol Evans Walker were of a very violent nature. Furthermore, Defendant’s own statements, including his statement that he would “take a battery charge if he saw Carol Evans Walker on the street,” show that he had the intent to carry out his threats. Defendant is a violent man who wrote violent letters, and in the Court’s opinion, fully intended to carry out his threats.
Order of 9/15/97 at 3 (citations omitted). Thomas argues that the district court considered impermissible evidence in concluding that the six-level enhancement was appropriate and, in the alternative, that the district court misconstrued the evidence presented to it. To the extent that Thomas’ argument requires us to interpret § 2A6.1, our review is de novo.
See United States v. Wilson,
While this appeal was pending, the Sentencing Commission issued an application note which addressed a circuit conflict regarding “whether or not conduct which occurred prior to the making of the threat can evidence an intent to cany out the threat.” U.S.S.G. § 2A6.1, Amendment 549. Although the amendment became effective after Thomas’ sentencing, we may consider it because it “clarif[ies] rather than substantively ehange[s] the Guidelines.”
United States v. Downs,
Here the government has conceded that the district court was referring to Thomas’ criminal record—prior conduct—when it called Thomas “a violent man.” But we have no means of knowing exactly which prior conduct the district court considered. And it was presented with quite a menu, since Thomas’ presentence investigation report (PIR) chronicled nine adult criminal convictions, including three for aggravated assault and/or battery. The PIR also listed various arrests in which no action was taken, including aggravated battery of a pregnant woman. But whatever this rap sheet says about Thomas’ propensity for violence, only one event is at all connected to Walker—the armed robbery which she prosecuted.
The robbery, however, is not analogous to what the Sentencing Commission had in mind when it directed courts to consider prior conduct that is “substantially and directly connected” to the instant offense. The cases that Amendment 549 cites favorably all involve prior conduct that was aimed at the recipient of the threats. In
United States v. Taylor,
for instance, the defendant conducted surveillance of his victims’ home and hired a private investigator to gather information about them.
See
Of course, the Sentencing Commission directed courts to look at “the facts of the case taken as a whole,”
see
Amendment 549, and the Eleventh Circuit recognized that the factors it set forth were non-exclusive and not always essential.
See Taylor,
Thomas further argues that the district court impermissibly considered the three letters that were not charged in the indictment. The record does not indicate which letters weighed into the district court’s § 2A6.1(b)(l) analysis, but we assume for the sake of argument that the court examined all five letters, not just the two charged in the indictment. Thomas has seized on dicta in
Sullivan,
where we speculated about whether a November 1993 amendment to § 2A6.1 limited the sentencing court’s inquiry to relevant conduct. As we explained in
Sullivan,
prior to the November 1993 amendment, § 2A6.1(b)(l) imposed a six-level enhancement “ ‘if the
defendant’s
conduct involved any conduct evidencing an intent to carry out such a threat.’”
When Thomas raised the relevant conduct issue, the Sentencing Commission had not yet issued Amendment 549. That amendment makes clear that § 2A6.1(b)(l) is not limited solely to relevant conduct, since the sentencing judge may consider all prior conduct that is substantially and directly related to the threatening communication. We are not certain whether Thomas believes that a portion of his relevant conduct argument can survive Amendment 549 — that is, whether he would assert that the sentencing court’s inquiry is limited to relevant conduct and prior conduct that is substantially and directly connected to the offense. This argument might find some support in the plain language of Amendment 549, which instructs courts to consider “both conduct that occurred prior to the offense and conduct that occurred during the offense.” § 2A6.1, Amendment 549 (em *839 phasis added). Compare § lBl.S(a) (instructing courts to consider all acts and omissions that occurred during the offense of conviction); see also § lBl.l(i) (“Offense means the offense of conviction and all relevant conduct under § IB 1.3 (Relevant Conduct) unless a different meaning is specified or is otherwise clear from the context.”). But we can think of no reason why consideration of prior conduct would be subject to fewer limitations than consideration of subsequent conduct. And adoption of the relevant conduct approach would lead to inexplicable results.
The three uncharged letters illustrate the' point. They were sent after the two letters charged in the indictment. They thus obviously are not prior conduct. They also are not relevant conduct. 1 As such, a sentencing court could not consider the letters if its inquiry were limited only to relevant conduct and prior conduct that relates substantially and directly to the offense. But if the government had charged Thomas with the last two letters that he mailed to Walker—instead of the first two—we would have no difficulty concluding that the other three letters were prior conduct that substantially and directly related to Thomas’ offense. The point is that all five letters may be probative of whether Thomas actually intended to harm Walker; § 2A6.1(b)(l) could not have been designed to arbitrarily preclude the district court from considering three of them. 2
We therefore conclude that Amendment 480—which made clear that a district court could consider the conduct of others for which the defendant is accountable under § 1B1.3—did not simultaneously
limit
the scope of the district court’s inquiry to
only
relevant conduct. We concede, however, that the plain language argument is plausible when considered strictly on its own terms. But it seems to us so lacking in any rational basis that we cannot attribute it to the Sentencing Commission. Accordingly, a district court making a § 2A6.1 determination should consider, in addition to relevant conduct, the “defendant’s overt activity [substantially and directly] connected to the threat.”
Carter,
Thomas’ final argument with respect to the six-level enhancement is that the district court should not have given weight to a comment that Thomas made to an IDOC investigator. When questioned about the letter that Walker received in October 1992, Thomas stated that “if he saw [Walker] on the street, he would take a battery charge.” Tr. 61-62. Thomas asserts that this was mere idle talk,
see Sullivan,
Given Thomas’ comment to the investigator, the nature of the letters themselves, and other facts — such as Thomas’ knowledge of Walker’s home address — the district court may have decided that a § 2A6.1(b)(l) enhancement was warranted regardless of Thomas’ prior criminal record. But Thomas raises one other objection to his sentence, and the government concedes that we must remand on this point. The distinct judge declined to group Thomas’ counts under U.S.S.G. § 3D1.2(b), which states that counts shall be grouped when they “involve the same victim and two or more acts or transactions connected by a common criminal objective or constituting part of a common scheme or plan.” Amendment 549 has clarified that multiple counts of “making a threatening or harassing communication to the same victim are grouped together under § 3D1.2.” Since we are remanding to allow this grouping, the district court should consider whether a § 2A6.1 enhancement is appropriate in light of facts that are properly before it.
AFFIRMED IN PART, REMANDED IN PART.
Notes
. The government argues that the letters fall within the parameters of § IB1.3 because they are part of the same course of conduct. This is incorrect. The same course of conduct analysis is inapplicable unless the letters—if charged as separate offenses—could be grouped as multiple counts under § 3D1.2(d).
See
§ lB1.3(a)(2);
United States v. Ritsema,
. Or, to illustrate the point more dramatically, consider a scenario in which a defendant, several months after sending a threat, shoots out the windows of his victim's car and truck, narrowly missing the victim’s child. This would not be relevant conduct under § IB 1.3. But it is undoubtedly probative of whether the defendant intended to carry through with his threat. And it is clear that if the shooting occurred before the making of the threat, the district court would be free to consider it.
