other officers.” (citations omitted). Guy, supra, 221 Ct.Cl. at -, 608 F.2d at 870. See also Sanders, supra; Boyd v. United States, 207 Ct.Cl. 1 (1975), cert. denied, 424 U.S. 911, 96 S.Ct. 1106, 47 L.Ed.2d 314 (1976). Perfect objectivity in the rating process cannot be expected or even hoped for. Guy, supra, 221 Ct.Cl. at -, 608 F.2d at 870-71.
In the face of this presumption, plaintiffs must do more, to invoke court intervention, than merely allege or prove that an OER seems inaccurate, incomplete, or subjective in some sense. The showing is not enough where an allegation, even if proved, fails to establish the presence of “factors adversely affecting the ratings which had no business being in the rating process,” id., or where there is no clear violation of a specific objective requirement of statute or regulation, or where there is no misstatement of a significant hard fact. Nor is it enough to impel us to act that the rater may now say that he scored the claimant too low. In Tanaka v. United States, 210 Ct.Cl. 712 (1976), cert. denied, 430 U.S. 955, 97 S.Ct. 1599, 51 L.Ed.2d 804 (1977), we held that a rater’s statement that his opinion had changed and that he would now rate plaintiff higher, absent any misstatements of fact in the OER, did not tender a triable issue on the accuracy of an OER. In Savio v. United States, 213 Ct.Cl. 737 (1977) , the plaintiff supported a challenge to the accuracy of an OER with a statement by the rater that the rating was not consistent with the rater’s high regard for the plaintiff, blaming this on his slight personal attention to the plaintiff’s performance of duties, words of caution he had received from his superiors on inflating numerical ratings in OERs, and his failure to include pertinent information in the report. Again, there were no allegations of misstatements of hard fact in the original rating, and we refused to order the removal of the challenged OER. See also Borgford v. United States, supra. In Stewart v. United States, 222 Ct.Cl. -, 611 F.2d 1356 (1979), we held that plaintiff’s allegation that OERs were inaccurate because his raters intentionally downgraded his ratings in order that he would show job progression was an insufficient ground for our voiding the OERs. Id., at -, 611 F.2d at 1358. See also Reid v. United States, supra; Wilson v. United States, supra.
C. Based on these holdings and criteria, the majority of the challenges to plaintiff’s OERs must be rejected.6 The ground for challenging the 1960-62 OERs is that which was found insufficient in Stewart, supra, and thus cannot be sustained here. The challenges to the September 1963 OER and the August 1970 OER are very similar to those considered in Tanaka, supra, Savio, supra, and Borgford, supra. The contentions are that the opinions expressed by the raters were not completely accurate or complete, not that the OERs were factually wrong or were influenced by “factors adversely affecting the ratings which had no business being in the rating process.” Guy, supra, 221 Ct.Cl. -, 608 F.2d 870-71.7 Accordingly, we find no error in the Correction Board’s refusal to remove these OERs.

The Correction Board’s decision, while lengthy in comparison with some Board efforts, is mostly conclusory. The opinion is more a catalogue of the contentions considered by the Board than an explanation of how the material and arguments presented were weighed and appraised. In these circumstances we give less deference to the Board’s conclusions than we would do if a reasoned explication had been forthcoming.

With respect to the September 1963 OER there is an assertion that the rater expressed dislike for the plaintiff on a single occasion at a bar. We view this allegation of a single and casual expression of dislike as comparable to the charge in Borgford that those rating officers were members of a nurses’ clique of which that claimant was not a member, and not as serious or significant as the allegations of the rater’s and endorser’s personal animosity and bias in Stewart, said to be due to Stewart’s having a Japanese wife (in that case there were “several statements by knowledgeable persons citing specific incidents,” and the issue was remanded, among others, for a hearing by the Correction Board).
