All Ashley needs is a silver for a lock in GPF, and a bronze for tie breaker. I think we are going to see a lot of silver and bronze for tie breaker and if you are already in 4th at one of the event, that will be really tough to get into final.
Unless of course no body other Miki, Yuna and Joannie has more than two GP medals, then it's anybody game.
Oh, yeah, there's no question that Ashley is in a much better position to qualify for the GPF. If she has silver she guarantees it (since five gold medals almost certainly go to Yu-na, Joannie, and Miki, and maybe one more to Miki, so 2 silvers is the next best anyone can do). If she has bronze she will be in for a tie-breaker.
Who gets the silvers will determine the remaining three places (suppose Miki gets her 2nd gold as the third seed). The thing is, since Mao has a silver and is already out of running with a 5th. There are two not unlikely scenarios that gives Caroline a fighting chance at GPF qualification if she can grab silver at SC. One is if Carolina wins silver at CoC, then another silver is accounted for and she's out of running (with a 6th). That also means that Rachael will have to get silver at SA to qualify (2 bronzes won't cut it).
That means so far 6 golds and 3 silvers accounted for (assuming Rachael gets a silver at SA) and two spots left for the remaining three silver medalists (Ashley from CoR, ? at NHK, and ? at SC). If Sasha wins silver at SA, then there would be three spots left for the three silver medalists of CoR, NHK, and SC.
If Carolina falters at CoC, then Rachael is likely to get silver, and whether she gets silver or not at SA, she will qualify. If she doesn't get silver at SA, Sasha is likely to get it and will not qualify.
Again, that's 3 silvers accounted for and two spots left for the remaining three silver medalists including Ashley so far.
Obviously, if Ashley hits silver again at NHK, then the silver medalist from SC will probably qualify (Caroline?).
The worst scenario is if Yukari beats Ashley for the silver at NHK (and Ashley gets bronze). Then Yukari will qualify, Ashley would still qualify, then even if Caroline wins silver at SC she will become first alternate.
Another total unknown is Mirai. If she beats Rachael and Carolina for silver at CoC, then she would qualify even if she gets beaten by Caroline at SC. But in this scenario, if Rachael settles for bronze behind Sasha at SA, then she will not qualify, and the last two spots come down to the three silver medalists at CoR (Ashley), NHK, and SC. Then Caroline better be hoping again that Ashley gets silver at NHK, and she herself gets the silver at SC.
So, not hopeless, but overall probability of Caroline still having a chance of qualifying for GPF by winning silver at SC is, I believe, about 50%. It all comes down to Carolina, Mirai, and Yukari, who are all a bit unpredictable.
