It's interesting that the only Senior event Adelina won until now (other than Russian Nationals) was 2011 Golden Spin. She is also the first Olympic ladies champion who has never stood on the World podium. That makes the sudden explosion of her PCS scores even more inexplicable.
It was bc she gave the skate of her life, skated with such spunk, skated in front of the home audience, skated like she wanted to win!
