at across the room distances, I am thinking you don't even need a front sight.
anywhooo...what I took away from reading the article on the study was that the researchers in my opinion did not sufficiently account far any gender based differences.
IIRC, all the SWAT team members were men. about half the shooters in the novice group were women.
it has been proven time and time again that women and men view the world differently, and in general men are more...ahem...visually oriented.
