I'm glad Ashley got this skate out of the way. She's human, I was wondering when she was going to make a mistake. Anyways, her score here was still higher than the SB of Nagasu and Gold, and this was very uncharacteristic of Ashley, whereas Mirai's URs and Gracies mistakes in the FS are pretty typical for them, so I'm not too worried for Ashley. She might not win Nationals but I'd be surprised if she wasn't top 2, and I think she likely will win as she'll have a PCS margin on Gold and Nagasu and is less likely to make mistakes or UR her jumps. Gold has never scored higher than 113 in the FS thus far, and Ashley got 115 with 2 falls, Mirai's scores at 2010 Olympics and 2011 4CC were high, but those competitions were also very inflated, apart from those two comps, I think her 115 from NHK was the highest she's gotten in a while. Gao can maybe hit 120 if she's perfect, but she'll need a good draw for the FS to do that, and once she makes one mistake, the scores seem to drop suddenly (as evidenced here). Zawadzki even when she's skated well in the FS internationally has never broken 110.
I don't expect Ashley to skate like this at Nationals, but even if she did, I have a hard time seeing her drop below 2nd.
