AMENDED OPINION
Dеfendant Casaneyl Valentine appeals his sentence for committing seven bank robberies on the basis that the district court erroneously departed upward by two levels in determining his offense level under the Sentencing Guidelines. The district court justi *1210 fied the departure on the basis that Valentine robbed seven banks, but, under § 3D1.4 of the Guidelinеs, which accounts for multiple groups of offenses, Valentine would only be punished for five of the offenses. Because the Guidelines only allow such departures for “significantly more than five units,” and we are convinced by the language and structure of this provision that seven units is not within the range envisioned by the Guidelines as being “significantly mоre than five,” we reverse the decision of the district court, and remand the case for resentencing consistent with this opinion.
I
Defendant Valentine pled guilty to robbing seven different banks in Memphis, Tennessee, on seven different days between September 17, 1993 and October 12, 1993. Valentine’s presentence report established а Guideline range of 130-162 months in prison, based on an offense level of 28 and a criminal history category of V. The presentence report arrived at this range by grouping the seven offenses into seven different groups, taking the offense level of the group with the highest level (26, in this case), and adding five levels pursuant to § 3D1.4 because Valentine’s seven groups of offenses earned him seven “units,” bringing him within the category of offenders with more than five units (§ 3D1.4 contains a chart, discussed more fully below, which adds five more levels to an offender’s offense level if he or she has “more than five units” in grouped offenses). Valentine qualified for a three-level reduction for acceptance of responsibility, resulting in a final adjusted offense level of 28.
At sentencing, however, the district court sought to correct what it perceived as the injustice of Valentine’s last two robberies going “unpunished” pursuant to § 3D1.4’s enhancement table that ends, by adding only five levels to the offense level of offenders with more than five units. 1 Accordingly, the district court departed upward by two levels, and sentenced Valentine to 180 months of imprisonment. The district court explained its decision as follows:
As I indicated earlier, my thinking is that the 3D1.4 grouping guideline does not take into account more than five offenses. The defendant has pled guilty to seven offenses, and I think payment is warranted for seven offenses.
***** *
The Court believes that under 3D1.4, the Court should increase the sentence by two additional units which takes into account that there are two felonies. There have been two felony bank robberies that have not been taken into account.
Counsel for Valentine objected to this departure to no avail at the sentencing hearing, and Valentine now appeals the decision to us.
II
We review decisions to depart from the sentencing guidelines for abuse of discretion.
Koon v. United States,
— U.S. -, -,
The plain language, however, resists a clear answer because it includes the inherently subjective term “significantly more.” Specifically, the Guidelines Commеntary states:
Inasmuch as the maximum increase provided in the guideline is 5 levels, departure would be warranted in the unusual case where the additional offenses resulted in a total of significantly more than 5 Units.
*1211 In unusual circumstances, the approach adopted in this section could produce adjustments for the additional сounts that are inadequate or excessive. Situations in which there will be inadequate scope for ensuring appropriate additional punishment for the additional crimes are likely to be unusual and can be handled by departure from the guidelines. .... An alternative method for ensuring more precise adjustments would have been to determine the appropriate offense level adjustment through a more complicated mathematical formula; that approach was not adopted because of its complexity.
USSG § 3D1.4, comment, (backg’d). Thus, the only directive to be gained from the “significantly more” language is that “just plain” more than five is not enough to justify departure — how much more is “significantly more” is unclear.
A careful examination of the chart gives us some evidence for interpreting what could be “significantly more than five.” The lowest number of units that could be “more than five” is 5)6, but that number is already covered as the very first portion of the category that requires оnly a five-level increase. The chart is not specific after this point, except for the general sense, inherent in the word “significant,” that the magnitude of the difference be more than the bare minimum.
The structure of this Guidelines provision, however, lends considerable support to our holding that, in this context, seven is not “significantly mоre than five.” This provision provides for a progression from “groups of offenses” to “units” to “levels,” the basic currency of the guideline scheme. Different offense groups (which can include one or several offenses) are assigned “units,” ranging from 0 to)6 to 1. When we examine the table that is set out in the guidelines, we can see a general pattern that increasingly large numbers of units are required to justify each additional increase in offense level. That is, § 3D1.4 does not simply add one level for each unit assigned to an offender. Rather, it adds levels as follows:
Number of Units Increase in Offense Level
1 none
1% add 1 level
2 add 2 levels
2)6 - 3 add 3 levels
316-5 add 4 levels
More than 5 add 5 levels
There are two plausible ways to measure this relationship between units of offenses аnd levels of punishment. The first is the number of units required to go from the beginning of one level to the beginning of the next level. Thus, 1)6 units is the lowest number that justifies a one-level increase; 2 is the lowest number that justifies a two-level increase. Therefore, an increase of )6 unit will take an offender from the bottom of the range that adds one levеl to the bottom of the range that adds two levels. Proceeding in this fashion, we can see that incremental amounts on the chart for this measure advance in the following sequence: \ \ 1, 2. This last increase means that it takes an increase of 2 units to move from 3)6, which is the bottom of the range that adds four levels, to 5)6 (more than fivе), which is the bottom of the range that justifies adding five levels.
Thus, even a simple continuation of the pattern would require an increase of a minimum of 2 units to reach the bottom of the range that would justify an increase of six levels. (More likely, there should be an increase of 3 or 4 units, depending on whether the progression of increases is linear or geometric.)
Consistent with this analysis, the hypothetical range that would justify adding six levels would only begin at 7)6, and thus Valentine, with his 7 units, would not fall within that range.
An alternative way of looking at the chart is to examine the width of each range; that is, the number of additional units that can be added without an increase in level. Thus, the lowest rаnge, which justifies an increase of one level, has a width of 0: it applies only to exactly 1)6 units. The same applies to the range that justifies an increase of two levels. If we look at the entire chart, the widths of the ranges increase as follows: 0, 0,)6, 1)6. Thus, when we look at the width of the range for the hypothetical increase of five levels, that range should be a minimum of 1)6 units, *1212 and more likely 2]é units or more, again, depending on whether the rate of increase is linear or geometric. Applying even this hypothetical minimum width of the range that justifies five levels would set that range as being from 5% to 7 units, and more likely even wider.
■Thus, by either means of computation, 7 units would fall only within the range for the adding оf five levels. An amount of units that falls comfortably within the range of a simple command to “add five levels” cannot be considered to be “significantly more” than would justify that offense level.
The point we are illustrating here, that § 3D 1.4 attaches decreasing marginal punishment to additional offenses, has been noted by other courts. Mоreover, it is explicit or implicit in other schemes found within the Guidelines, and has a strong policy basis. In
United States v. Pearson,
While useful in that they support our reliance on the Guidelines’ emphasis on declining marginal punishment, the
MacLeod
decision that a putative 10 units permitted departure and the
Pearson
deсision that 8 units permitted departure are-not comparable to this case
*1213
because their respective courts considered the nature of the underlying offenses as justification for the departures. The
MacLeod
court considered the four uncounted victims (4 additional units, effectively) significant “[gjiven the potential psychological harm to the young victims of this type of offense....”
MacLeod,
We differ with the other circuits that allow the decision of whether an offender deserves an upward departure pursuant to § 3D1.4 due to the presence of significantly more than five units to be confused with the general social harm caused by the underlying offenses. The Guidelines established an elaborate system to weigh all, or virtually all, of the facets of an offender’s criminal activities. The base offense level assigned to a particular offense generally accounts for the seriousness of the offense, while the sections for specific offense characteristics and the various sections on adjustments for offender and victim characteristics account for these other variables. Section 3D1.4, on the other hand, is meant to account solely for the numbеr of different offenses or groups of offenses that an offender committed. Departure from the chart in this section should thus be based solely on the number of units assigned to an offender, not the underlying nature of the units.
To approach this chart otherwise and interpret its concept of “significantly more than five” to involve some subjective weighing of the social significance of the underlying offenses usurps the role assigned to the Sentencing Commission in setting base offense levels, and turns the section into a catch-all provision justifying departure whenever a court simply believes an offender with more than five units deserves additional punishment. The whole point оf the Guidelines is to reduce or remove this type of discretion from the sentencing process and assign certain numerical values to certain facets of an offender’s criminal activities. To • confound the facet of the Guidelines dealing with the magnitude of criminal activity with other facets of the Guidelines, such as the subjеctive social harm caused by the particular type of offenses involved, reduces the precision and uniformity of sentences. The type of concerns articulated by the MacLeod and Pearson courts are clearly important, and might justify departure under other, more general provisions of the Guidelines, such as § 5K2.0. These concеrns, however, should not be weighed in the decision of whether an offender has accumulated “significantly more than five units.”
Ill
Because 7 units is relatively close to the edge of the chart used in § 3D1.4 and almost certainly would not have even exceeded the probable next cut-off point had the chart been expanded to include a category for a six-level increase, we conclude, as a matter of law, that 7 units are not “significantly more than 5,” so as to permit departure in this context. In so concluding, we note that our mode of analysis was essentially to do that which the Commission itself avoided as too complicated — reconstruct a mathematical formula to handle multiple groups of offenses. Nonetheless, we see this method as the most principled means of answering what the drafters of the Guidelines meant by “significantly more than five.” While we cannot point to a particular number of units as the cutoff after which a district court is justified in departing, we can conclude that this point should lie above a line reached by simply extending the general direction of the relationship established in the Guidelines by one more level.
We thus VACATE defendant Valentine’s sentence, and REMAND his case to the district court for resentencing consistent with this opinion.
Notes
. See chart atp. 1211.
. The Chase court did not specifically еquate these offenses with units, but rather only commented that “[w]e find the instant case to be one in which the additional offenses (numbering nine) resulted in a total of significantly more than five units." Id. at 491. Given that the discussion suggests these were individual robberies and one individual attempt, however, it is reasonable to assume that each instance wоuld have garnered one unit pursuant to § 3D 1.4. Were this true, the defendant in Chase would have had a total of 15 units.
. We note that the
MacLeod
court justified departure pursuant to § 3D1.4 on the basis that "[t]he district court relied on at least four additional offenses, and four uncounted victims makes this an 'unusual case' resulting in a total of 'significantly more than five units.’ ”
MacLeod,
.See, e.g., the loss charts in § 2F1.1, which assign additional offense levels for fraud and other related crimes according to the amount of loss caused by the offense. Offenses causing more than a $2,000 loss lead to an increase of one level, while a loss of more than $5,000 will yield the next level of increase — two levels. However, as one moves further up the chart, it takes increasingly larger increases in loss to trigger the next offense-level addition. Thus, at the end of the chart, offenders causing $40,000,000 worth of loss suffer the addition of 17 levels, while to trigger an 18-level increase an offender must have caused $80,000,000 worth of loss.
