Sorry, but I'm afraid Angela Wang, much as I love her, fits in the same category as Mirai and Courtney (Polina's unfortunately persistent injury puts her in a slightly separate category). Angela is 21, has competed at every Senior Nationals since 2012 and has never finished higher than 7th.
Internationally, she has two gold medals to her credit: a JGP medal in 2012, and a 2017 Bavarian Open gold medal. She has been on the podium at some summer and Challenge events, including a silver last summer at the Philadelphia Intl, bronze at the 2015 US Intl FS Classic, and silver and bronze at 2014 Challenger events. But she has come up short at the bigger events: She finished 8th and 9th at her two GP events, one in 2014 and one in 2015. She was 9th at 2018 4CC.
Angela just seems to crumble when faced with serious competition---it's almost as if she doesn't believe in herself. I certainly wouldn't put her in the same category as Bradie Tennell and Ting Cui.
You bring up compelling facts with Angela. It looks like Bradie and Ting are our best bets.
