Shiz wasn't looking this poorly though. I mean she medaled at both her events but she had to face Irina/Mao at one event and Mao/Sasha in another. She actually beat Sasha in the long program in France (barely but still) and she had the fourth highest scores (and the third highest of the eligible ladies!) that year. She was looking a LOT better than she was from the previous season and she wasn't looking completely out of it.
As for Mao hitting her jumps in practice, a lot of people were commenting on how her jumps didn't look so great in the pratice clips... sigh. It seems that Mao decided to not only fix her flutz, but changed the technique on her flip. I think it was all just way to much.
I agree with ur statements on Shizuka but Mao still has the second best senior score. One reason we where shocked at her score at france was probably we all know she could easily score in the same range as Yuna.
Again in winning this competition Miki hasn't set a huge score, but that is the range in which she scores and further was enough to win the competition.
Most concerning part is mental toughness of mao, she seems not able to handle the pressure. Hope she learns to relax, do some yoga or something.
