Back then, Polina's biggest problem was her programs and packaging. She did have some rotation problems but, so did Mirai. I'm sure I missed part of this conversation but, Ashley's the one who was held up that year not Polina.
Mirai also skated terribly a couple weeks later at 4CC and finished 10th against a weak field and didn't even score 160 points showing that sending her to the Olympics for having just one decent competition all season would have been a mistake.
