I once looked at performance in the Olympics. West African and their diaspora dominate the short distance, long jump and triple jump. But not other sports. With certain other sports, others dominate or are more successful than their percent of the human population. North Africans in middle distance, East Africans in long distance. As for the decathlon, no race or ethnic group dominates.
If you look at baseball, teams become increasingly left-handed as you elevate from high school to college/low minor leagues to major leagues.
If you look at mathematics and science, the Nobel Prize winners are almost all male.
So what about any of this. Let the chips fall where they may. As long as the competition is fair, let the best man or woman do the job.
UCLA lost because the other team was better. It doesn’t matter white, black, US, international, right- or left-handed.
When my team is winning, I don’t see anything but the uniform. I will admit, when my team is losing, my mind wanders.
The only qualification I’d put to this is that it’s unfair to allow genetic men, or women who dope up with testosterone to compete as women. If you’re going to allow people with the strength of men to compete as women, you might as well shut down women’s sports.
Well done! If you've done that work I assume you've read this:

Your point is also made often by Thomas Sowell. Basically, there's no reason to expect equal outcomes of any groups within an area of performance to begin with.
