Opinion for the Court filed by Circuit Judge GARLAND.
George E. Cone, Jr. filed suit in United States District Court challenging the Army’s refusal to amend his Officer Evaluation Report. The court concluded that the Army’s refusal was arbitrary and capricious, and directed the Army to improve Cone’s rating. We reverse.
I
Cone served as a captain in the United States Army and commanded an infantry company during the Persian Gulf War. 1 After the war, his supervisors completed an Officer Evaluation Report (OER) assessing his performance from June 14, 1990 to June 13, 1991. An OER is used to evaluate an officer’s performance and career potential. See Army Regulation 623-105, at ¶ l-6(a) [hereinafter AR 623-105]. At least two of the officer’s superiors prepare the report — a “rater” who directly supervises the officer and a “senior rater” higher in the chain of command. Id. ¶ 3-1. Cone’s rater was his battalion commander, Lt. Colonel Stephen S. Smith. His senior rater was his brigade commander, Colonel James C. Riley.
The OER form contains blanks that require the rater and senior rater to provide both numerical and narrative assessments. Part VII of the form is reserved for the senior rater, who evaluates the officer “by comparing the rated officer’s potential with all other officers of the same grade.”
Id-¶
4-16(b). In Part VII(a), the senior rater is to check one of ten blocks that rank the officer’s potential against that of all other officers of that grade. According to Army regulations, the evaluation is “based on the premise that in a representative sample of 100 officers of the same grade or grade grouping (Army-wide), the relative potential of such a sample will approximate a bell-shaped normal distribution pattern.”
Id.

This means, the regulations continue, “that in a representative
Once completed, the Army compares the senior rater’s assessment of the officer to the senior rater’s rating history for all officers of the same grade — -known as the senior rater’s “profile.” Id ¶¶ 2-5, 4-16(d)(5)(a). “The purpose of the profile is to place the rated officer’s OER in perspective by revealing the senior rater’s general rating tendency.” Id ¶ 4-16(d)(5)(a). By comparing a specific OER to the profile, the Army can discern whether a particular officer performed above, at, or below the “center of mass” — i.e., the median ranking — of the officers ranked by the same senior rater.
In completing Cone’s OER, senior rater Riley checked the second block from the top. Of eleven captains rated by Riley during this period, he ranked seven in the top block, three (including Cone) in the second block, and one in the third block. See J.A. at 147. According to this profile — which was included in Cone’s OER— Riley’s center-of-mass (“COM”) was the top block. Cone’s rating was therefore below center-of-mass for the group even though he was rated in the second-highest block, which corresponds to the top 2-3% of captains Army-wide.
Cone appealed his OER to the Officer Special Review Board (OSRB), which is charged with reviewing requests to correct erroneous military records. See AR 623-105, atf 9-2(i). He contended that “[t]he senior rater blocking ... does not accurately portray my potential and may penalize me when viewed by future boards.” J.A. at 144. As support for this assertion, he supplied affidavits from Riley and Smith indicating that Riley “did not intend for [Cone’s] OER to reflect below center of mass performance,” and acknowledging that Riley had failed “to tightly manage” his senior rater profile. Id at 150.
The Special Review Board denied Cone’s request. See OSRB Decision at 4 (July 2, 1993) (J.A. at 143). The Board rejected the affidavit from Riley, noting that Army regulations preclude “statements from rating officials that they did not intend to evaluate as they did from serving as the basis for favorable action on appeals.” Id; see AR 623-105, atíí 5-32(b)(2), App. 11N-2(b)(3). The Special Review Board also noted that Riley had submitted “virtually identical” memoranda in support of appeals by five other captains he had similarly rated below center-of-mass. 1993 OSRB Decision at 2 (J.A. at 141). 4 Although the Board recognized that there “was a persistent failure by the [senior rater] to manage his profile for [captains] in such a way as to preclude any unintended below-COM ratings,” it concluded that Cone had failed to adduce “clear and convincing evidence” (as required by the regulations) to rebut the “presumption of regularity” in the OER. Id at 3-4 (J.A. at 142-43) (citing AR 623-105, at ¶ 5-32).
Cone next appealed to the Army Board for-Correction of Military Records. See 10 U.S.C. § 1552(a)(1). Based on the same evidence, Cone urged amendment of his OER to reflect a center-of-mass rating. The Correction Board rejected his appeal, concluding that, despite Riley’s inability “to establish a ... profile for captains that approximated a bell-shaped normal distribution,” Cone’s rating accurately captured Riley’s assessment of Cone’s performance compared to that of other officers of the same grade. Correction Board Decision at 4 (Apr. 26, 1995) (J.A. at 128). The Board noted that its conclusion was also “supported by the type of comments used by the [senior rater] to distinguish between a top block officer and a two block officer.” Id.
After losing before the Correction Board, Cone filed suit in the United States District Court for the District of Columbia, alleging that the Board’s denial of his request violated the Administrative Procedure Act, 5 U.S.C. § 706(2)(A), and asking the court to correct his records.

Specifically, Cone argued that Army regulations require a senior rater to rank officers along a bell-shaped curve, and that Riley’s failure to maintain a profile hewn to that curve constituted arbitrary and capricious action. Although the district court found that the regulations “do not mandate that each senior rater maintain a bell-shaped-curve distribution,”

The Secretary of a military department, acting through a civilian board, “may correct any military record of the Secretary’s department when the Secretary considers it necessary to correct an error or remove an injustice.” 10 U.S.C. § 1552(a). An officer’s OERs are presumed to be “administratively correct” and to “[represent the considered opinions and objective judgment of the rating officials at the time of preparation.” AR 623-105, at ¶ 5-32. An officer seeking a correction must prove “clearly and con

we do so under an “unusually deferential application of the ‘arbitrary or capricious’ standard” of the Administrative Procedure Act.
Kreis v. Secretary of the Air Force,
Cone contends that Riley’s failure to adhere to a bell-curve distribution, and the Army’s refusal to correct that failure, constituted arbitrary and capricious agency action in violation of Army regulations. The regulations, however, do not require adherence to a bell-shaped curve; rather, they state a “premise” upon which senior raters are to base their evaluations:
The senior rater’s evaluation is made by comparing the rated officer’s potential with all other officers of the same grade, or grade groupings.... His or her evaluation is based on the premise that in a representative sample of 100 officers of the same grade or grade grouping (Armywide), the relative potential of such a sample will approximate a bell-shaped normal distribution pattern.
AR 623-105, at ¶ 4 — 16(b). As the district court itself said, this regulation does “not mandate that each senior rater maintain a bell-shaped-curve distribution” in each rating period.
Cone,
Even without a statistical analysis, it is clear that Riley was lax in following the rating guidelines. The Special Review Board itself determined that, over a series
Moreover, we would be hard pressed to find a reversible “error” in Cone’s record even without the clarification provided by the senior rater’s profile. Under the regulations, the senior rater’s obligation is to compare “the rated officer’s potential with [that of] all other officers of the same grade” Army-wide. Id. ¶ 4-16(b). The rating box in which Cone was placed represents the top 2-3% of all Army officers of the same rank. There is no evidence in the record that Cone’s true' abilities place him in the only higher category — a category reserved for the Army’s top 1%. See id. ¶ 4-16(c). Indeed, the principal flaw to which Cone points — Riley’s inability to adhere to a bell curve — indicates only that Riley tended to inflate his officers’ ratings above the curve: he consistently placed most of his officers in the top few boxes on the rating chart, despite the instruction that those boxes be reserved for the top few percent of all officers in the Army. See, e.g., 1993 OSRB Decision at 3 (J.A. at 142) (noting profile periods in which Riley gave top-block ratings to 22 of 61, 12 of 19, 6 of 11, and 26 of 32 captains). Although this could suggest that Cone’s ranking should not have been as high as the one Riley gave him, it certainly does not establish that he should have been ranked even higher. 9
In support of the contention that he was misrated, Cone offers a post-evaluation affidavit in which Riley states that he “did not intend for [Cone’s] OER to reflect below center of mass performance.” J.A. at 150. But the Correction Board reasonably refused to credit the affidavit on the basis of Army regulations providing that “[statements from rating officials that they did not intend to rate [an officer] as they did” will “not be used to alter or withdraw a report.” AR 623-105, at ¶ 5-32(b)(2);
see id.
App. ¶ N-2(b)(3). The rationale for these regulations is an understanding that raters may attempt to retract otherwise accurate assessments when requested to do so by their disappointed officers. Such post hoc statements by rating officials, the regulations explain, “often reflect retrospective thinking, or second thoughts, prompted by an appellant’s non-selection or other unfavorable personnel action claimed to be the sole result of the contested report.”
Id.
The Correction Board’s refusal to credit Riley’s affidavit is
Cone also asks us to consider affidavits, authored by senior Army officers, that contend that the adjectives Riley used to describe him in the narrative section of the OER indicate a center-of-mass rating.
See
J.A. at 96-99. Both affidavits were written in November of 1998 — after the district court complaint was filed and long after the close of the administrative proceedings. Because the affidavits were not part of the administrative record, we may not consider them on appeal.
See Environmental Defense Fund, Inc. v. Costle,
In conclusion, we observe that the district court’s remedial order reveals just what a quagmire we would enter were we to uphold Cone’s challenge to his OER. The court directed the Army to amend Part VII(a) of Cone’s report “to reflect a center of mass rating.”
Cone,
At bottom, Cone argues not that he was graded too low in comparison to all officers of his rank, but that he did not get the full benefit of his superior’s inflated grading curve. Because we conclude that this does not constitute cause for requiring the Cor=-rection Board to amend Cone’s evaluation report, we reverse the decision of the district court.
Notes
. Cone was promoted to major in October of 1996.
. In a normal distribution, most of the data points are "clustered near the mean, and the density or relative frequency of the numbers decreases with increasing distance from the mean.” David W. Barnes & John M. Conley, Statistical Evidence in Litigation 140 (1986). "If the frequencies with which the numbers in the normal population appear as the result of random experiments are plotted on a graph, the figure resembles a bell-shaped curve.” Id.
. The Army has recently altered its regulations and OER form, and has dispensed with the ten-block rating system. See Army Regulation 623-105 (Apr. 1, 1998); DA Form 67-9 (Apr. 1, 1998). The citations in this opinion refer to the regulations and forms that were in effect at the time of Cone's evaluation.
. The Special Review Board further found that of nine below center-of-mass ratings made by Riley and processed by the Army between August 1990 and February 1992, he supported or offered to support appeals by at least seven of the subject officers. See 1993 OSRB Decision at 3 (J.A. at 142).
. Cone also challenged his nonselection to the Command and General Staff College, a challenge the district court found nonreviewable.

. Cone’s appellate brief asserts that his incorrect OER also violated his rights under the Privacy Act, 5 U.S.C. § 552a(e)(5). Neither Cone’s complaint nor the district court’s opinion addresses such a claim, and we therefore do not consider it here.

. Cone notes that Riley wrote on the OER: "This evaluation does not reflect a downturn in performance, rather I have restarted my profile.” J.A. at 147. Army regulations permit a rater to restart his profile when necessary to convey his intended evaluation to selection boards and personnel managers. See AR 623-105, at ¶ 3-12.1. Although Riley's comment means that Cone’s second-block rating should not be regarded as a downturn in Cone’s own performance, it says nothing about where he ranks in comparison with his peers.
. By the same token, we decline to give any weight to the Special Review Board’s conclusion that the words Riley used in Cone’s OER were “not comparable” to the words he used to describe other officers whom “he did in fact place in the top block COM.” 1994 OSRB Decision (J.A. at 159). The Army successfully argued below that the court should deny Cone discovery of the OERs of the other officers upon which this comparison was based, even in redacted form, on the ground that they were not part of the administrative record before the Correction Board.
See Cone v. Caldera,
. The other alternative — lowering the ratings of some officers now in the top block in order to make the second block the center-of-mass — would only further complicate the problem discussed in the following text.
