They've never removed the retired, split, non-Senior eligible, etc.teams at the end of the season from the Top 24 SB list in the past for the purposes of determining GP spots. Are they making a change for next season?
My understanding is that they don't remove retired and split teams from the WS list, unless the Fed notifies the ISU to.
At the moment, there are only two events left that qualify for the SB list: Worlds and WTT, which tends to inflate scores. The cut-off in Dance right now is Soucisse/Firus' 172.27. The next skaters on the list scheduled for Worlds are:
Wang/Liu (169.11), Turkkila/Versluis (168.34), Koch/Nuechtern (165.31), Reed/Ambrulevicius (164.11), Tessari/Fioretti (162.94), Yanovskaya/Lukacs (158.11).
Barring disaster, I expect Wang/Liu to bump S/F from SB 24. They are CHN #1, and they have politik none of the other do. (Although I haven't looked at the judges list, 8+ points in ID is a huge gap.) Ushakova/Nekrasov might be vulnerable to Wang/Liu getting the CHN major Fed boost and Turkkila/Versluis skating the lights out, with new respect for their SB high skates at Euros. Evdokimova/Bazin should be safe as #22 with SB of 175.62.
