Quoting from the study:
Greater male variance is indicated by VR [Variance Ratio]> 1.0. All VRs, by state and grade, are >1.0 [range 1.11 to 1.21].
If a particular specialty required mathematical skills at the 99th percentile, and the gender ratio is 2.0, we would expect 67% men in the occupation and 33% women. Yet today, for example, Ph.D. programs in engineering average only about 15% women.
Larry Summers in his infamous talk, was explicit about this point:
...if one is talking about physicists at a top twenty-five research university, one is not talking about people who are two standard deviations above the mean...But it's talking about people who are three and a half, four standard deviations above the mean in the one in 5,000, one in 10,000 class.
The expected gender ratio at 4 standard deviations from the mean you find a ratio of more than 3:1
The Wall Street Journal correctly reported on this when most other media did not
