You still don't understand the flaw there if you agree with that.
"The degree or magnitude of the advantage is therefore critical"
You seem to believe that any advantage is too much...
But what the regulator said re: 10% isn't being disputed here. Why would you expect intersex males (yes I know they're officially classed as females in terms of their legal identity, pls don't start feigning confusion re: gender and legal identity again) to perform at that level? Essentially you'd want the subset of however many people with Caster's condition to contain a few people who are as fast as the very fastest males in the world... which isn't likely with any given, much smaller, sample of males as already highlighted. It's really basic and you don't seem to ba able to understand it.
The only confusion is why you keep mentioning gender identity and legal identity, despite the many times I point out I'm deliberately ignoring that and only focussing on what actual, real, professional medical doctors have stated.
It seems as if you're continually returning to that deliberate misrepresentation in order to refute it...
And yes, I would expect to see anyone with a confirmed "male advantage" performing at least as fast as the average male in the 10-12% above females bracket. Even between the absolute fastest and the slowest women, of the 1300 in the Berman-Garnier's 2127 Observations, the difference was only 3%, though.
But more importantly, a 46 XY DSD is only banned from five events - They could still quite happily compete in 17 of the 22 events documented in the B-G 2127 study, despite this supposedly-massive "male advantage" they have.
What you're failing to argue, or even mention, is the
potential for biological advantage that
MAY lead to a performance advantage, but since potential does not equal actual, we're back to the CAS arbitration that "The degree or magnitude of the advantage is therefore critical" and "a 1% difference may not justify a separation".
Also: all I've done is state what the regulators have already decided" is iffy when you're actually just referring to some comment by the CAS that that advantage may not be sufficient, the regulator still requires Caster to limit her testosterone if you're going with this fingers in the ears, just arguing the status quo according to the regulator approach.
Yes it does, and it's absolute ******* bull ****.
The IAAF can now basically do whatever it likes with those regs, without oversight, without the possibility of appeal, and with only the flimsiest of suggestions of slight advantages derived from single source flawed data... Makes you wonder why all them smart science people are challenging the regulations, dunnit?
