Well, Marai did land her triple Axel after puberty. How many times? 2 maybe. I would not consider landing a jump a few times the same as "having" the jump. And Tuktamysheva did not lose her 3A after puberty.....but did we ever see her land one pre-puberty?
The Quads.....probably too early to tell what will happen.
From NBC Sports
"Last season, according to skatingscores.com, three women – Trusova, compatriot Anna Shcherbakova and Kazakh Elizabet Tursynbaeva went clean on eight of an aggregate 19 quad attempts. "
That is less than 50%. And all three of those ladies seem to have retained their pre-pubescent figures.
Eteri is great at teaching those tiny things to jump, rotate, and land.
It will be a while until we see ho can hold on to what with boobs and hips.
