You are assuming she will lose what tech advantage she has, not improve anything else, and that Bell and Tennell won't lose anything as they get older, which definitely happens as well.
Yes, I am assuming that. Based on how she was jumping last year, it didn’t look very sustainable to me. But she is still young enough that a coaching change might get her a better technique and kill my argument. Also, I agree with you that Bell and Tennell could certainly get worse as they age. I understand why the US fed is investing in Liu for the future, I just think that as it stands today, she’s no medal threat internationally. But neither is Bell or Tennell. And the Olympics are not today, so there is that.
