Once you get out of anti-trans hate groups, pretty much all the scientific research shows that within about a year of starting hormone therapy, any potential physical advantage is gone. Particularly if you're focusing on testosterone, since there's plenty of cis female athletes with abnormally high testosterone levels who either don't get scrutiny, or even more ridiculously, do get scrutiny as if their natural advantages over other athletes are somehow "unfair" and makes them less of a "woman".
Like, if you read over that report, it is not a broad analysis of the extant science. It's "an advocacy group with an agenda fed us a talking point and we engaged in literally no further examination of the issue and just presented that advocacy group's agenda without further consideration". It's a political document pushing an agenda and cherry-picking the sources (that often have no scientific basis) which agree with the conclusions those composing the report wanted to draw.
