Your example assumes that the AI isn't taking your 80/20 split and integrating that back into the test. Even if your ever so nebulous "biological differences" exist, you have already acknowledged that an objective measure of programming ability can be measured independent of gender, what TFA and "the left" are talking about is the distortion of that objective measure by lazily applying that correlation back into the measuring system, eg. making a 80/20 into a 90/10 split, then a 95/5 split, which in your example would be a waste of society's resources and would earn whoever made the AI a death sentence for incompetence.
