Kaetlyn's 4CC FS was the best she's skated all season, and I was duly impressed. She wanted to end her season on a high note, and she succeeded in doing that. Good for her!
OTOH, Gracie's FS at 4CC was the worst FS she's skated all season and I was very disappointed, but not that surprised. Gracie has never skated well at 4CC. I don't think she likes the long travel to Asia so soon after US Championships.
When she has a disastrous SP like the one at 4CC, she usually gets mad and has a bangup FS, but that didn't happen
this time. You can be sure you'll see a different Gracie in Boston.
As for the other ladies improving and impressing, Alaine wasn't at all impressive at 4CC. She messed up the 3z combo in the SP, and started off the FS the same way, and the old habits just crept right back in: df, so, ur. She just seemed tired and disinterested, almost like Gracie. Veronik was her usual smiling self, but she is several tiers lower than Chartrand and Daleman.
