I know that, I completely agree that her form is fine. From my intermediate Russian that’s how I translated Buyanova’s quote. Maybe someone else can confirm?
Your translation is correct.
But, the only "unadequate" thing is what that coach doing with her skaters...
P.S. Sorry for the offtopic at the Nastya's fanfest. My post is about Buyanova as a coach, Nastya is fine.
