She won one match, then lost the next - in neither case were there any complaints or controversy about her having unfair advantages. Clearly her advantage wasn't all that spectacular.

Then in 2022, she did make it to the final of the world championship in her weight class - where she lost, see link for the video of that match. I know absolutely nothing about boxing, but it doesn't look to me as if she's hitting so much harder than her opponent, nor am I hearing that mentioned in the commentary.

Amy Broadhurst, the winner in that final, has now posted her views online, speaking out against the abuse Khelif has received - and questioning just how reliable the IBA's decision to ban her from the 2023 world championships really was, and how the IBA might have ulterior motives in kicking up a fuss about it now during the Olympics, after the IOC banned them from having a say in the boxing at the Olympics due to corruption issues (which I guess answers my earlier question).

No doubt the line needs to be drawn somewhere, whether it's a question of testing testosterone levels or some other kind of test for upper body strength directly - but it's obviously complicated and it doesn't seem like the IBA's decision last year was necessarily the only possible right answer there.
