She was in tears at LP because Caroline Zhang was under tremedous pressure due to her miscues from SP. She was relieved that Caroline withstood the pressure.
Netnuts, thanks for the translation! I thought I would add a little bit more details from Caroline's coach's blog.
On the scoring error in the SP:
"When Caroline's long program was about to end, people saw me being very emotional. In fact, I was really moved! That's because two of Caroline's triples were downgraded in the SP, but I believed there was no problem with the 3 flip. When I had a chance to have chat with the head judge, they realized that they really had pressed the wrong button. During the competition, they tried to give back the points, to make up for their earlier mistake, but because of technicalities in the rules, it was not possible to correct Caroline's score. In the end, she only got 7th in the SP."
Note: in Chinese verbs don't have tenses, so it's ambiguous from her writing (to me) the exact order of what happened -- whether her discussion with the head judge led to the attempt to correct the score, or whether during their discussion they admitted that they had realized the error and even tried to correct it, but that in the end they realized nothing could be changed. To me, this point is mute. Every skater/coach has the right to talk to the judges about their scoring, and if there's an obvious mistake then it seems perfectly reasonable to want to have it corrected it (after all you've worked so hard all year, in fact all life, for these few minutes' skating in front of the judges). But obviously rules are rules, and if they say once the next skater has started skating you can't change it anymore, then that's that. It just means that the judges were doubly incompetent -- making the mistake in the first place, and then not realizing that it was against the rules to change the score.
On her tears:
"Caroline's mental state was greatly affected by the placement (of 7th in the SP), execution problems, and issues with the judges/tech panelists, we had to somehow leave behind the disappointments (of the short program). Therefore, when I saw how Caroline gave her everything to attack every element in the long program performance, I was really moved by her fighting spirit, I was so happy for her, and so proud of her!"
On the future:
"After the competition, everything starts anew at square one. Both experiences of success, and the lessons of failures, will become a source of learning for future training and competition..."
My take is that those judges were holding grudge against Caroline because they didn't like the media hype and decided to seek revenge on her.
To be more precise, I think it was more the tech panel and not the judges. True Caroline should've gotten higher PCS in the LP, but she was skating in the penultimate group and statistical analyses have shown that skating order has a significant and dominant effect (over other extraneous factors) on PCS scoring. So that wasn't necessarily bias against HER. But the tech panel wrongly downgraded her 3Lz in the SP, graded her spiral sequence and last combo spin both level 3 (when she's been consistently graded level 4 in int'l competitions), and turned a blind eye to Ashley's flutzes and some of Mirai's UR's.
The trouble with giving the tech panel so much power is that it's a small group (3 people, though we don't seem to really know the exact power structure, which is probably more concentrated on one person than evenly spread among all three), versus a large judging panel that hand out the GOE's and PCS. It's much more likely that individual biases can have a big impact on the final score and thus placement through the tech panel than the judging panel -- the large size of which mitigates against individual biases. If just one or two people on the judging panel really dislikes Caroline for whatever reason (just look on FSU forum to see how many Caroline haterz there are!), then that's enough to have a discernible effect.
If Caroline's 3Lz hadn't been downgraded (a mandatory -3 GOE, like Ashley's 3F out of footwork at 4cc), she would've place either 4th or 5th, right around Kimmie's score, and she would've skated in the last group -- in which case she would've probably gotten slightly higher PCS. Plus the tech panel really should've caught Ashley's flutzes, and some of Mirai's UR's. And so the final outcome of the top four might have been somewhat different.
Tech specialists and judges are human too, and they have human opinions and make human mistakes. It makes no sense to separate the judges and tech specialists on separate panels, and make one very large and the other very small, and pretend that biases don't enter into the latter group. Somehow judges' countries are announced, but ISU pretends that tech specialists represent the ISU and not the individual countries. Come on, who are we kidding?!
Stupid rules like the tech panel is allowed to change its calls EXCEPT for downgrades and edge calls -- well, that's pretty idiotic too. Arbitrary or not, at least make these rules consistent!
