E. Statistical Evidence
Reichhold submitted at trial its 1986 Affirmative Action Plan, PX 42, which showed that for the Inorganic Chemical Industry, of which Reichhold was a member, there was a 7% presence for women in the category “officials and managers,” i.e., 2,811 out of a total of 40,027. The presence for women in this category at Reich-hold was, according to the report, 15%. Id. Halbrook attacked these numbers, asserting that by the end of 1987 the number of women in the “officials and managers” category at Reichhold had declined from seven to four, corresponding to a reduction in the percentage of women in the category from 15% to 7%.

II. Discussion
A. Legal Principles
The legal framework for resolving sex discrimination claims under Title-VII is well established, and principally set forth in McDonnell Douglas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973) and Texas Dep’t of Community Affairs v. Burdine, 450 U.S. 248, 101 S.Ct. 1089, 67 L.Ed.2d 207 (1981). The plaintiff has the initial burden of demonstrating, by a preponderance of the evidence, a prima facie case. This Halbrook has done. She has shown that she belongs to the protected group; that she applied and was qualified for the promotion to General Counsel; that she was not promoted; and that the position was given to someone not in the protected group.
The defendant then is required to articulate some legitimate, nondiscriminatory reason for the employment action that it took. The defendant need “only produce admissible evidence which would allow the trier of fact rationally to conclude that the employment decision had not been motivated by discriminatory animus.” Burdine, 450 U.S. at 256, 101 S.Ct. at 1152. It is proper for an employer to rely upon a supervisor’s evaluations in assessing the employee’s performance in connection with an employment decision. Meiri v. Dacon, 759 F.2d 989 (2d Cir.), cert. denied, 474 U.S. 829, 106 S.Ct. 91, 88 L.Ed.2d 74 (1985); Lieberman v. Gant, 630 F.2d 60, 67 (2d Cir.1980). Indeed, past performance is the best qualification for promotion. Grant v. Morgan Guaranty Trust Co. of New York, 638 F.Supp. 1528, 1537 (S.D.N.Y.1986).
Thereafter, the plaintiff must prove by a preponderance of the evidence that the employer’s profferred non-discriminatory reasons were a pretext for discrimination. McDonnell Douglas, 411 U.S. at 804, 93 S.Ct. at 1825; Burdine, 450 U.S. at 253, 101 S.Ct. at 1150-51. To establish pretext, plaintiff may demonstrate that, despite the reasons articulated by the defendant, a discriminatory motive led to the challenged decision, or that the explanation offered by the employer is not worthy of credence. Burdine, 450 U.S. at 256, 101 S.Ct. at 1152. Pretext can also be shown by demonstrating that what defendant offers as the reason, while partially true, was not the determining factor in the promotion decision. Hagelthorn v. Kennecott Corp., 710 F.2d 76, 82 (2d Cir.1983). In other words, “[pjlaintiff is not required to show that [sex] was the sole factor in the employer’s decision”. Getter v. Markham, 635 F.2d 1027, 1035 (2d Cir.1980), cert. denied, 451 U.S. 945, 101 S.Ct. 2028, 68 L.Ed.2d 332 (1981).
Accordingly, Halbrook, in order to establish pretext, is not required to show that the reasons offered were false, but only that they were not Reichhold’s only reasons, and that the plaintiff’s gender made a difference.
Parcinski v. Outlet Co., 673 F.2d 34, 36 (2d Cir.1982),
cert. denied, 459 U.S. 1103, 103 S.Ct. 725, 74 L.Ed.2d 950 (1983). However, “to the extent that the employer ... goes beyond merely articulating a neutral reason ... to substantiating that reason by proving that it has a sound and factually supported basis, the employee’s task of showing that this reason was a pretext will be more difficult.”
Wade v. New York Telephone, 500 F.Supp. 1170, 1178 (S.D.N.Y.1980) (citing
Lieberman v. Gant, 630 F.2d at 66).
On the other hand, as our colleague Judge Conner has observed, it is clear that the plaintiff seeking to prove a claim of sex
