Ashley is a complete pro and knows how this sport is. You win some you lose some, national championships score are often outside the skater's control subject to XYZ... she knows more than anyone how it works in this sport, especially having lived through Sochi and how her outspokenness on important issues 'may' have affected her scoring/overall standing with certain judges, and her 4th place ranking at Olympic year Nationals (taking Mirai's spot) affected her perceived ranking. National Championships are often more about the strategic game federations plays upon the rival of nations. IMO, Mirai was given her perfect chance to win everything, but did not deliver

, Ashley likely to be appointed second (they probably hold her a bit back for Mirai? her obvious UR didn't help),
Karen is about setting up the future (Polina) and really she is the only one delivered on the day. One can scrutinise over everything including the PCS, but if you really consider everything, the scoring is understandable. She probably could have been given a few more PCS by reputation but lose overall (the correct ranking as it is now), but it is not like she wasn't a benefactor of past judge's 'discretion' as well, and knowing her, this will light a bigger furnace and she will rock at worlds.
