Anyway, the question is not, was 2014 Kim better than 2010 Kim, but rather, was 2014 Kim better than 2014 Sotnikova. Anything else is a red herring.
I do not think that this conclusion is warranted. I do not believe that the Sochi judges said to themselves, well, she got 9.25 at Vancouver, and this is better, so I'll give a 9.50. IMHO figure skating judging just doesn't work that way. In reality, the relation between the quality of the performance and the PCSs is, in fact, pretty murky.So apparently, the judges thought her choreography was worse than those seasons, that they gave her a higher CH score. Doh!
