You will never find a woman that has the same testosterone levels that a man identifying as a woman.. it's genetically impossible and that's unfair.
Men, especially athlete, are around 30 nmol/l. At the very least 6 times over your weird case scenario.
I'm sorry but women don't have testicles so they can't naturally produce high levels of testosterone, you won't be able to twist stuffs enough and make scenario weird enough to prove that.
Oh, and Khelif chose to have a female phenotype so she could compete in the female category in the Olympics? Get real. There are many other women in the same situation.

Uh, yes you will... The entire purpose of taking estrogen is to bring down testosterone to female-level.
Ever heard of testicles ?
If so, there was no point in dividing into groups.
That said, I am sure athletes and governing bodies could agree on a better solution than outright banning- for example all it takes is a group that pairs a freakishly long armed swimmer with not, and they compete as pairs. Or an open group- maybe someone without freakishly long arms will find a way to win.
Anyway, it’s sports, people will min/max everything you let them, and we know from history they may bend or break rules as well. At the end of the day someone has to make a rule and enforce it, over time it will evolve.
