but then men will triumph in most of disciplines force-based. I agree with you that a 70kg man athlete is equivalent to a 70kg woman athlete and is fair to make them fight, but how many men can work to reach that category? How many women? You will end, statistically, with 90% of top athletes 70kg as men.
Maybe 50kg category could have a different target and you would see something like 60% women and 40% men, who knows.
