I've been thinking about this today: as we continue looking towards Worlds, with the quad limitation in the SP, the best thing that non-triple axel, non-Russian skaters can do to help themselves is to do really well in the SP in hopes of skating as late in the final group as possible to force larger PCS gaps. If they're really lucky and Anna/Sasha make mistakes, they could push them into the second half of the second-to-last group. There are realistically only so many skaters that can be ahead of Anna/Sasha after the SP. Aliona, Rika, and You have the triple axels and if they land them, that's basically half of the final group filled. Skaters like Kaori (when she's peaking), Mariah, and Bradie could do well enough in the SP to maybe compete for some of the other spots. Maybe Eunsoo too if she can get her jumps back and consistent.
Of course, if Anna and Sasha land all or most of their quads, there's not much that can be done, but this seems like the best gameplan for skaters that can't upgrade their tech content this season. This would also really help Rika and Aliona, who are closer to the quadsters in scores and for whom medals may be decided more on the margins of PCS/GOE/deductions for falls. Ironically, there are many skaters right now that are making errors in the SP and doing much better in the FS.
(Under the assumption that Sasha, Alyona, Anna make the team)
SP order also goes by World Standings. Currently, top 6 that will make it through to the final group: Satoko, Kaori, Rika, Bradie, Tursynbaeva, Bell. Sasha will probably surpass Eunsoo (7th), and have enough to surpass Bell (after GPF and Euros). If Tursynbaeva doesn't make it to Worlds, Sasha's into the final group. If Zagitova/Tuktamysheva/Medvedeva make it to the team, they will push Sasha back out. It's complicated, but Shcherbakova and Kostornaia will most likely be in the 2nd to last group.
Not being in the last group sometimes makes judges subconsciously give lower scores. Not that this would matter that much, but it would in tight situations (and to determine FS final group).
