Yes, and it's likely the other senior National podium spot is Kaori, so meaning there is virtually only one National podium up for grabs for the senior skaters. So whoever gets up there will be considered for the second spot, and then there's still the third spot to be filled. If the women are all roughly equal, it will come down to the other criterias.
Back in 2021 (for 2022 Olympics), Mana came up top because aside of the Nationals podium, she had that NHK silver (Wakaba had GP France bronze) as opposed to Mai and Satoko, who didn't win any medal at all at the GP series. Even though, Mana's best total score at NHK is lower than both of theirs. Of course this "comprehensive judgement" will go either way depending on what JSF wants, but with very little possibility for the seniors to make it to the Nationals podium with Mao Shimada and Kaori there, every single thing can help IMO. And I'm talking from Ami's perspective here- even if she flops at Nationals, any win in the international circuit is a win for her international reputation regardless, which she will need for the next quad.
But I get you though- Wakaba's snub in 2018 is probably the one that stung the most, especially because she did everything right except making it to the podium at Nationals. But every year the context is different (and 2026 Olympics has 3 spots compared to 2018 Olympics 2 spots) and I think Ami has the potential to present herself as the Kaori of 2017-2018 with this win.
