I have no idea if there is any kind of strategy from eg Canada.
Thing is-
Trans ID is personal isn't it. While the IOC will have to know to do tests etc. Surely the decision on whether to go public is up to the athlete.
I tried to find out but couldn't find anything on IOC site etc. I would put money on that being the case though.
So I don't think anyone has any idea really. Certainly there has been and is speculation over some athletes but I mean who knows.
Re talent pool being tiny. That's of people who have internal ID of trans and are v good at sport I assume.
Thing is it's a massive loophole and some countries will do anything to win.
Doping generally sometimes it seems without the athletes knowledge.
East Germany and the women who were put on testosterone with no care for future health issues etc. I'm not sure that the women knew, I wouldn't be at all surprised if not.
Etc.
To compete in female cat you need to have testosterone below a certain level for a year.
The level is within the lower range of normal for men and 3x higher than normal for women.
The testosterone norms for males have a lot of studies etc saying they are not representative/ need looking at again but that's another thread.
Point is that countries who will do anything to win can and will-
Find males with talent who have naturally low testosterone (I suspect that exist, studies mentioned say norm is too narrow and lower is normal for enough men to make lower range lower)
And/ or find those who are good at sport but not quite good enough for the men's, who will for whatever reward/ coercion etc agree to lower T for X years (5 maybe or whatever - it wouldn't need to be forever) to compete for the country in the women's events.
That is just OBVIOUSLY going to happen.
So. All in all. Not good.
