I'm happy Gracie was able to redeem herself but I'm not entirely convinced she's gotten over her nerves yet. She did have the luxury of skating without as much pressure. I seriously doubt if she believed she had a shot at gold sitting in 9th place more than 10 points back. There was pressure of course, but nowhere near what Ashley, Agnes or Mirai faced at the top. Good for Gracie to use that to her advantage and deliver a phenomenal technical program but what would have happened if she was in that last group with a legitimate shot at winning? The fact is she has yet to put together two convincing performances...
I do think she was overscored. Given her mistakes in the SP, the judges were pretty lenient. They kept her close enough to get back into it. Her LP was great in terms of the jumps but the program itself was not impressive at all. I think her PCS were overly generous but I'm not surprised; it is nationals after all and after landing all of those jumps the judges were going to make sure she got onto that team.
Given Mirai's instability and Agnes still being a wildcard, Ashley and Gracie are a good world team. However, neither of them would have medaled with the performances they gave this year. Neither will have room for errors like that at worlds where they won't have the luxury of national judges to boost them.
