Not all the abilities measured by IQ are that important to education; see the last two sentences in this comment. Calculations like yours would underestimate the ideal number of women and Jews in academia, and for all I know (admittedly little) that may also apply to African-Americans.
My measure is a little crude; it uses IQ scores without dividing them into fluid/crystallized or verbal/nonverbal and that does have a cost in terms of accuracy. Unfortunately I don’t have the time or energy to do much better than a back-of-the-envelope calculation, not to mention my access to census data blows now that the Federal Government is shut down. This is part of why I didn’t bother looking at Asian-White or Male-Female differences where the numbers are smaller and the breakdown of scores is messier.
But at the same time; a 1sd difference (either the −1 for Black Americans or the +1 for Ashkenazi Jews) in a highly g-loaded test is such a heavy finger on the scale that I can’t imagine how my numbers would be off by the order of magnitude required to call the modern proportions “reasonable.”

Sure, I didn’t mean that modern proportions are reasonable; mine was just a nitpick.
