Your math obviously doesn't make any sense, since say a 65/35 representation of men versus women among people who score a perfect Math SAT doesn't mean there is a 65% probability of finding a man with that characteristic and a 35% probability of finding a woman with that characteristic.

I was thinking more like this: consider giving everyone a goodness score. At first, let's say the goodness score is entirely based on mathematical ability, which skews strongly in favor of men. Then, let's make the goodness score based 50% on mathematical ability, and 50% based on an independent criterion that skews in favor of men, but less strongly. There should be more women who achieve a certain goodness score under the second set of criteria than the first. That's what I mean when I say that considering additional criteria is dilutive.

Besides that, all your metrics skew in favor of men. But out of the various metrics that go into being a good programmer, I think mathematical ability is the only one that skews in favor of men. Studies show that female students get higher grades, because they are more attentive over longer periods, have more patience and impulse control. Also, in terms of programming teams, I think being social and communicative is far more of an asset than being competitive.
