My thoughts:
Zhang: She skated well, but I'm surprised her triple-triple was ratified. It should've been downgraded, imo. Frankly, her toe jumps are horrid and shouldn't get + GOE. It's especially jarring because all her other elements are beautiful. Her spins are gorgeous, her positions are very precise, and then you see those jumps and they take me want to scream. I think her straightline steps needed more spark, and she needs more speed, power and ice coverage. Probably her best performance of the season. I'm in awe of her consistency.
Nakano: Wuzrobbed, imo. Great performance and her spins are probably the best in the world. They are so fast and she gets so many revolutions.
Kostner: Just as I was letting my inner Carolina fangirl out, she singles the axel. Her triple-triple was gorgeous. Performance-wise, this was her best yet. Her edges are amazing, and I feel like she deserves a higher skating skills score.
Kimmie: I like her a lot, but the triple-.triple was severely under-rotated. I think she's peaked. She's not flexible enough for high level spins, and her triple-triple is gone. Shame, she's a nice skater.
Mao: I guess you can score 59+ on a program without a solo triple jump if your name is Mao Asada. That TES score - wtf? My only guess is that her spins and non-jump elements got high levels and positive goe. They're all beautiful., especially her spirals and steps Still the score seems incredibly inflated.
Yu-Na: Again, beautiful non-jump elements, and nice lutz and axel, but I don't think that's a performance that merited a season's best.
