I've forgotten more track & field in my 40+ years in the sport than you've even dreamed about knowing.
Sorry. You know nothing about track. Wilson was the best woman of the last decade. Semenya ran 1:54.25 in 2018 with ten times the testosterone and XY chromosomes. Niyonsaba ran 1:55.47 behind her in Monaco in 2017, now barred from the event by ten times the testosterone and presumably also XY chromosomes. Then third in the last decade is Wilson, 1:55.61 behind them in 2017. Mu at 1:56.07 is next best since 2008. I count 14 athletes from the former Eastern Bloc (counting 1989 Quirot) or China ahead of her. Also, there is a likely DSD, Semenya's former coach from Mozambique. (There were rumors about Pamela Jelimo. I don't know the story). So, basically almost all proven dopers or DSD ahead of her. That leaves Elly van Langen, the only athlete not known or suspected to be DSD or a doper or from a state-sponsored doping program ahead of her. That is awfully good. She's also two time World Bronze medalist, two time indoor World silver medalist, and golds in World under 18 and World under 20.
