Skating is also about blade control and it's most definitely an athletic aspect. After having analyzed the performances as much as possible, I've got to say the judging of the step sequences was crap. Sotnikova's step sequence had rough edges all the way through it and I saw nothing wrong in Yu-Na Kim's LP footwork sequence that should drop it to a Level 3. In the SP, yes, she made some edge mistakes that deservedly dropped the level, but in the LP her sequence hit the requirements and was executed FAR better than Sotnikova's.
Combine that with bad PCS judging and Sotnikova not being called for underrotation on her 3Lutz+3Toe< combo (Sotnikova has NEVER done this combo fully rotated in her entire career; she's always had a technique issue on the toeloop off the landing of the lutz and tried to do 3Lutz+3Loop in the past instead) and I'm officially upset with this result. It definitely still should have been pretty close, but she was massively held up and Yu-Na deserved it in the end; if Yu-Na's PCS were even just 2.5 points higher than Sotnikova's, that would be enough in my book. The fact that Yu-Na only got 0.09 more in PCS is an outrage.
