It doesn't.In tennis a 14 UTR whatever wins against a 13 UTR whatever. UTR is your effectiveness rating against every other player. Same in chess with ELO.
The issue is woman would disappear from profesional sports. Sinners 16.27 rating means that he double bagels Sabalenkas 13.29 essentially 100% of the time. The 500th ATP player has a UTR of 13.81, half a point is quite a bit stronger, do he's still very much stronger than Sabalenka. You probably have to start looking well into the thousand somethings for something that is consisently beaten by her.
Only the top 200 players make money, the top 100 good money, and the top 50 ridiculous money.
So women would not be in something like top 2000 of tennis players or worse. Which would basically remove any incentive for women to participate in pro tennis at all.
