I'm not sure what to say about Amber's scores. They are much more generous to her than other skaters.
A 9.5 and five 9.0's given for skating skills to someone who skates on two feet? It's not a criticism, it's simply an observation. It's mainly two footed skating. When Isabeau comes back she'll be getting 10.0 for skating skills if they are giving 9+ to Glenn.
A 5 and a couple of 4's for a telegraphed 3A with no running edge?
The 3Lo at this point is a 2Lo given she's almost 270 degrees before even leaving the ice.
On the 3-3 combo, the 3T was at least a q. The 3T had 225 degrees prerotation too.
Liu started well in the free skate, got away with no call on the 2A in the sequence (clearly underrotated don't know how they miss this), but just ran out of energy and there wasn't much power left for the combo in the second half, the step sequence, big mistake on the spin. It feels a little like a hastily put together exhibition program as well with the moving the arms and bopping to the music. It seems like maybe she doesn't have much of a dance background, so maybe they need something that plays to her strengths like with the SP.
It's hard to say whether Liu or Glenn deserved it more, but I'd have to give it to Liu. Glenn defintiely got looked after by the judges more.
Sarah probably should feel a little aggrieved she had two solid performances relative to the top two they really hold her back on PCS the huge 7 point difference between Amber and Sarah is not justified. The 71 PCS Amber receives is what Isabeau was getting (probably a touch overscored as well but justifiable for a beautiful skater like Isabeau), whereas a two footed skater doesn't deserve that kind of PCS.
You can see the temptation USFS has giving such a scoring boost to Isabeau every time, because apart from her jumps she's a class above any of these skaters, but those jumps are already not rotated on most jump elements and the jumps will only become much harder now.
The big PCS they give Glenn at these domestic meets feels like the USFS trying to gaslight ISU judges, and in a way it has worked because she started to get a big PCS push internationally as well because she was always a low 60's PCS skater until recently, and I don't think anything has really changed with her skating. Maybe 1 point, maybe 2 points at most higher than before
