She doesn't need PCS of 26 to stay below 80. Let's face it, she's not likely to get higher than 33-34 in PCS in the Short, and her GOEs are likely to be a little lower too, based on the GOEs she received in Beijing and what others are receiving. If Amber and Ami's best 3As get mean GOE marks of a little over +2, then Adeliia's isn't going to get +3 like she did here.
She definitely still has a very good chance of scoring in the high 70s, and sure, maybe even in the 80s with a generous panel (as so often at the Olympics), but not 86. High 70s would most likely still be enough to be at least in the top 3 after the SP, definitely in the top 6.
