I don't know about her speed or glide or what she deserves for SS, because I've never seen her live, but Levito is a very expressive and stylish skater in general, and I don't see where her other PCS are inflated. Top skaters don't have that much variation in PCS, even when they have technical difficulty, unless they struggle for a long time. It's the way Jason Brown has kept his career going. When she skates "poorly", Levito is still averaging mid-80's. Maybe if Lin-Gracey or Everhardt is named to the World team and skates blinders at 4C's she'd have a chance of 8's at Worlds, but probably not without doing that.
Levito has only been off the podium twice in her senior international career: at her first Worlds and at last year's GPF, where she had a very weak SP. And that includes all three competitions she was in this season.
Her Skate America score this year was 14 points under last year's SA score, with most of that drop in the SP, where she hasn't broken 70 yet in 2024-5. She has been 3/3 with total scores in the mid-high 190's, which is around what Higuchi and Yoshida scored at GPF. There are only six Women who averaged over 200 points in their two GP events: Sakamoto, Glenn, Higuchi, Chiba, Kim, and Sumiyoshi. Yoshida averaged 195, barely above Levito's 194+.
At this point in the season, Levito is second in WS points. If she doesn't compete at 4C's, only Yoshida and Kim can pass her with 4C's points, and Hendrickx with a combination of Euros podium and points from one or two internationals. (She has two open slots.) Neither Glenn nor Chiba can catch her with a combination of a win at 4C's and at an open slot international. The worst she can start is first in the last group in Boston. Her 68 SP score from Skate America would have put her in the final group in Montreal, and that's without Championships inflation. Her 61+ at Nebelhorn would have put her in the third-to-last group with Kurakova, Mikutina, Chiba, Schizas, and Taljegard, again, without Championship last group inflation. And, yes, different judging panels, etc., and scores tend to rise at championships, but as general benchmarks, I don't see how she skated so badly this season, especially since no one but Glenn has shown any consistency.
It's plausible that she's injured. It's plausible that she's in the middle of a growth spurt and has lost confidence in where her center of gravity is. We just don't know where she is now. But if she's skating decently by Nationals, I don't see her being off the team. We keep waiting for Liu to hit her stride, and we knows she's a competitor, but she's not there yet either.
