Imo, Ms Wilkes is an excellent observer. The comparisons between Plushenko and Buttle are very astute.
My only comment on the differences in the scores whiich Ms Wilkes was quite correct to mention, it that the judges are going through a new system which they are not yet experts.
I believe they can only watch just so much of a program and can not digest the entire routine of any one particular skater. It is not like judging gymnastics which a judge looks at moves on a balance beam or high bars for less than one minute. There is no music to grab you for interpretation, etc. (Diving even less than 10 seconds per trick.)
In the case of Plushenko vs. Buttle, I can understand a judge assuming beforehand that there will be no competion between the two. Evgeni is the better (and, imo, he is) so therefore subjectively and without malice, he is not as critical of Plush as he is about Buttle. Imo, this is not deliberate on the part of the judges. It is just that the new system is a toughie for them to grasp the entire program of any one skater and will force them to fall back on reputation and the 6.0 ratings.
I don't have a solution to this, yet I do like the CoP in principle.
