Any of the girls that had GP assignments that podium will make it. No one has been good enough to warrant an exemption. Last Oly year, only a GPF victory would have automatically qualified, and Higuchi being the only one who qualified for GPF got no benefit. JSF usually goes with the podium unless it is injury to a superstar like Mao or Hanyu, regardless what the official criteria says. That doesn't apply here. JSF takes Nationals very seriously. However, Im sure they will take season performance along with other issues into account when it comes to how strict or lenient the judges are with different skaters.Not that it makes a difference in standings, but Wakaba got 205.27 at Skate Canada.
Sadly, I think Rino's chances are almost gone by now. Her injury has prevented her from showing anywhere near her best on the GP, and she'll need to do her career best performances at Nationals to even be considered at this point. As for Rika, I think she'll be on the team as long as she makes the podium, but we haven't heard any promising updates about her condition, and Nationals is less than a month away.
