I don't know anything about it. As far as I was aware genetic testing was not necessarily accurate. This was the first site that I'd seen which claimed a method was 100% accurate and I came across it when I was searching for background on the method that the World Boxing Commission is planning to use for the Olympics. https://www.espn.com/olympics/story...xing-mandates-sex-testing-boxers-competitions
I know Simone Biles is trying to do what's right here... And maybe I'm missing something... But I don't think a transgender category in all sports helps anybody. I'm not necessarily opposed to it, if it works and makes everyone happy. I just don't see how it helps much. *Edit* I don't think there are enough competitors to create these specific divisions. This just seems like it would fully exclude transgender athletes.
