I think, just like with other troon related statistics, they really don't make up a large percentage. They're generally just the biggest drama magnets, so it seems like there's a disproportionate amount of them. They're also especially prominent at the GDQ events, which typically get the most coverage. ESA has been fairly active with online stuff during the virus and I don't recall there being a single troon at any of the events.
Slightly related, but the non GDQ events also tend to have more legit female speedrunners participating. I've heard through the grapevine it's because they're more comfortable/feel safer at those events compared to GDQ, but it's also just entirely possible only one or two people said that and it's just easier to get accepted at the other events due to there being less submissions/travel logistics etc. It just always struck me as funny that GDQ likes to present itself as this beacon of diversity, but outside of a few troons and a small handful of female runners, it really is just a bunch of white dudes. Granted, I'm sure there's more in the audience, but still.
