Yes, I think some people get the 'wrong idea' if they don't actually follow skating closely, since they see year after year it appears there's a new young Russian girl at the top or close to the top of the World podium. But it isn't like the Russian federation is intentionally throwing older skaters under the bus to make this happen which I think you honestly don't have to dig very deep at all to find proof of. The federation supports who is performing well, period, and doesn't prop up those who performed well last year (or need to because the field is SO deep). Just look at Tuktamysheva. In years when she performs well, she gets sent to major competitions; in years when she doesn't she does not. However, before last year people were writing her off, saying the Russian federation had written her off and so on. The second she started to perform well again the federation supported her fully. Next year, if she starts performing well again, they'll support her fully too.
They also even send skaters who are struggling to MANY competitions to try to help them improve their performance and their scores. Leonova was sent to more B's than almost anyone this year, and 'underperforming' skaters like Artimieva who are sort of hanging around the very very bottom of the top tier and don't really have a prayer of getting sent to Euros or Worlds still get a lot of international assignments. Tukt also continued to be given as many assignments as she wanted this year even once it was abundantly clear she wasn't going to get her last years form back.
Basically I just do not buy that the federation holds any of the ladies back intentionally or unintentionally. To the contrary I think all their top ladies are given a fair chance, and those that can perform the best go to Worlds and Euros, period. That it isn't the same people year after year is a sign to me that the system is working, not that it isn't.
