Not at all. If the skill requirement is lower for women to get into the same position as men, is it not rational that, on average, those women will perform poorer than the men?

Imagine they did the same thing for university entrance: men need all prerequisite courses and a 3.8gpa, whereas women need only 75% of prereqs and a 2.9gpa. It only makes sense that the women are going to score lower in exams/flunk out, since their initial starting point was, on average, further behind.
