Why are all these innocent questioners asking for more evidence not familiar with the existence of the evidence they are asking for?
Considering they feel so strongly about it, they should already have seen all this.
Regardless, Lia went from not being in the front of the pack, to being in the front of the pack:
“By the conclusion of Thomas's swimming career at UPenn in 2022, her rank had moved from 65th on the men's team to 1st on the women's team in the 500-yard freestyle, and 554th on the men's team to fifth on the women's team in the 200-yard freestyle.”
65th to 1st in one category, and 554th to 5th in another.
It is fair to say there was a significant increase in rank post-transition.
From Wikipedia:
> Thomas began swimming on the men's team at the University of Pennsylvania in 2017. During her freshman year, Thomas recorded a time of eight minutes and 57.55 seconds in the 1,000-yard freestyle that ranked as the sixth-fastest national men's time, and also recorded 500-yard freestyle and 1,650-yard freestyle times that ranked within the national top 100.[4] On the men's swim team in 2018–2019, Thomas finished second in the men's 500, 1,000, and 1,650-yard freestyle at the Ivy League championships as a sophomore in 2019.[4][3][13] During the 2018–2019 season, Thomas recorded the top UPenn men's team times in the 500 free, 1,000 free, and 1,650 free, but was the sixth best among UPenn men's team members in the 200 free.[14]
To focus in on her just-out-of-highschool low ranking, and imply that it's weird that she improved by the time she graduated, is deliberately disingenuous (not on your part, but on the writer's.) She had already won 3 silver medals as a sophomore on the men's team, and was the best on her team in all but one event.
This power lifter set regional junior records as a young man then quit the sport and didn't compete for 16 years. After transitioning she went on to win gold medals in numerous international competitions as a woman.
