I thought Miki's PCS overmarked. I think that she did pretty well. But I don't really think she deserved 8.0's that some of the judges gave her. She didn't have much speed and her program doesn't have many transitional foot steps or choreos. Although she seemed to have been working on her posture and arms, her arms still looked awkward and stiff. Her posture was slightly better than the last year, but not really good, esp. in her spirals. Although I wasn't surprised when Yuna or Mao got 8.0's from some of the judges, I don't get why this performance deserved 8.0's, except that she is the defending world champ skating in front of the home audience.
On the other hand, I think Carolina had great speed, a lot of interesting, sophisticated moves, good connection with the music, and nice appeal to the audience. I feel that Caro deserved better PCS than Miki for this SP performance.
