Probably so she can easily win the junior title. She was 4th last year when Polina won. She had a issue with URs last season, so I think it was good she stuck around in juniors for another season. And under the new rules she won't be GP eligible until the 2015-2016 season.Thank you, I didn't know.
But why? As for me Karen's skating is more "seniorish" than Polina's.
