A lot of this depends on whether there are any rule changes, but if the rules are the same as last year, the following skaters and teams are guaranteed spots for GP or are eligible for selection, with the additional caveat that ... Team Challenge Cup ... WTT counted towards SB's; only Ladies and Men could count towards the SB list, as singles will compete both SP and FS, while Pairs and Dance teams will only compete in the free.
The ISU SB total scores list haven't changed since before Team Challenge Cup, and so it appears the scores from TCC are NOT being counted as ISU season or personal bests.
* = 2016 Worlds top 12 men/ladies or top 10 pairs/dance
[ ] = ladies are too young for GP (not yet 15 as of July 1, 2016)
