Polina indeed said that one of the reasons why she left was competition in that group --> but as in that surrounding it was not possible to cure her back. So what did you expect her? To stay there and risk becoming crippled? She wasn’t even able to train at full force in a less competitive surrounding.It might not have caught your attention (although it's strange because you quoted me), but I said "probably also because of her health", so I'm aware of her back problems. And Polina said herself that she didn't like the constant competition in the Eteri group. She went to more relaxed environment. She chose the easier way. And easier way is not the way to success.
And I again give you a hint that it’s not appropriate to post negative things about skaters in their fanthreads like indicating that Polina’s main reason for switching coaches was taking the easy way (why is it only fans of a certain coach who so very often have to be reminded about it? )
