That kind of sounds like a soar loser comment. The Russian girls won by over 25 points.. "Personal subjectives" why "his favorite" is better, are just that.. "personal subjectives".
Cui skated very well, she absolutely deserved her 3rd place, over Sinitsyna. Sinitsyna, however, even if sent to JW, is russian junior lady #6 (based on season's performances/results, except for nationals). She is behind the top 3 girls and Kanysheva and Tarakanova. So basically Cui did not beat the top 2 at the competition. She probably would not beat Kostornaya (unless a meltdown), and was not likely to beat Kanysheva and Tarakanova as this season shown.
My "personal subjectives" on Cui are: she has strong jumps, she makes a good effort at being balletic, graceful, and musical. She is NOT mature, and her "balletics" looks like a "young girl who is taking ballet classes, and learned all the generic moves and postures". To me, there is nothing special YET! about Cui. She is good for her level.
