Everyone knows that Cup of Russia was the biggest farce of judging last season, in conjunction with scores from Sochi. Lipnitskaia winning with 3 triples (and a score of 118), B/S winning with a fall in their FD and higher PCS than W/P. Then of course Sotnikova in the individual event in Sochi, Plushenko in the team FS in Sochi being held up even though other skaters should have certainly placed higher, and both of V/T's FS throw errors being neglected. After Sochi/CoR, who would wanna compete in Russia again?
Yes, the judging at Cup of Russia was unfair. There was a bias in favour of the Russian skaters. And we definitely saw that in dance. All the non-Russian dance teams took large hits in their marks. It happened to G&P as well, who dropped 10 points from their NHK score earlier in the month. You could particularly see it in the levels given for some of the elements like footwork sequences where the Russian dance teams received high levels, and all the non-Russian teams received low levels.
But let's be honest about one thing - Canadian skaters do tend to get a bit of inflation of their own at Skate Canada. I'm Canadian myself and am willing to admit that. It's not as bad as it was at Cup of Russia, but there tends to be an edge given to Canadians in some events.
