Fischer: 1. e4 "Best by test" Fischer famously scribbled "best by test" on one of his score sheets after playing 1. e4.

Yet when I look at chess.com's database of games, 1. d4 yields a larger win %age for while than does 1. e4.

Was Fischer wrong?  If not, what changed to make this so?
Aside from the fact that the difference is only .3% at master level games on chess.com's db, I think Fischer was referring to his own personal results.

A search on chess tempo for Fischer's games reveals that this is the case:

e4 (51.3% win)
d4 (15.4% win)


update: The statistics above are skewed because Fischer never played d4 as white. See comments. Still, my initial point is valid. It was his preferred opening. I don't think .3% makes him wrong.
