I’m with demarinis in looking forward to the likely prospect of him doing the GP (and maybe 4CC or Worlds?) next season. Hopefully he’ll be spared further injuries.
If Dai is chosen for Worlds, he will gain enough points and PB and get 2 spots in GPS next season. If he is not, he will get a senior B at best and will not get enough points or PB, which means he will not get a GPS next season.
I'm skeptical that he will be chosen for Worlds even if he finishes after Shoma, though. The criteria for the third spot is very ambiguous, and basically JSF can pick anyone they want, and their priority is on young skaters. I don't think they will give the host spot at NHK Trophy to Dai next season either.
