I think the opposite. Ashley won the LP at Nats this year with an error-filled performance; a strong case could've been made for placing Rachael and/or Caroline ahead of her. Ashley has one of the worst flutzes ever, and she wasn't even given a '!' mark for it in the LP. Meanwhile, Caroline received the '!' mark on both her flip and lutz, something that has never happened before. The loss of that third spot could very well cost Caroline, IMO. Nats judges don't seem to like her. The only way she can guarantee herself a spot on the Olympic team is if she skates 2 perfect programs at Nats next year, with a 3-3 and no downgrades, and even then I'm not sure she won't be marked down. In addition, she'd have to be blazing on the GP circuit.
As long as she skates a clean SP, Ashley could skate a LP like she did at Nats this year and still make the Olympic team, IMO. Rachael is a virtual lock.
