Plushenko's transitions marks are always to high as he had often said you don't need them, just jump.
Kostner's skating skills are about the best in women's field, so she should always get these marks quite high. This year she has grown in presentation really much.
PCS are not jumps and it's why they get are to mark independently. I always think skaters who are god jumpers get high PCS, but it shouldn't be so. Jumps get a lot of credit in the technical marks; the skating skills, presentation, execution, transitions, choreography, the artistry ... should reflected much more independently in PCS.
