Good question, I don't know how many women go to the gym. From what I've seen the majority of women in my city are willing to just not date their entire 20's if they can't get a Chad('waiting for Chad'). Which as you point out, mathematically most women are not with Chad.
They would be smarter to not even go to university and just get an easy job and dedicate themselves to going to the gym to increase their odds of getting Chad.
Also thinking about it, at the university there must be way more girls than guys.. yet even normie guys are struggling to get a date in university. Showing definitively women just won't lower their standards.
