Ievleva has only 2A, 3Loop, 3Sal and 3Toe, and Karademir has only 2A, 3S and 3T, and neither was proficient with the jumps they did have. Marchei was AWFUL in both SP and FS. Gedevanishvili landed only the 2A in her SP, and she still had jump problems in the FS, singling her lutz and flip. Binshu Xu hardly landed any triples in her FS and she got -GOE on most of the jumps she did land. Mai Asada had a decent SP but her FS was zzzzzz and she got dinged heavily for underrotations and flutzes.
When skaters have iffy jumps, they tend to concentrate on the technical aspects of their skating. They don't relate much to their music, their flow is choppy, and they look tentative and uncomfortable. All of that gets reflected in their PCS scores.
Mira actually landed more of her jumps cleanly than Hughes did, and she got a lot less underrotation deductions than Zhang. But her speed wasn't anywhere near as good as Emily's or Caroline's, she didn't relate to her music as well, and her basic skating technique is far more flawed than theirs.
So while Mira outscored the poor jumpers on the PCS side, she lost ground to skaters who had lower TES but outscored her in PCS.
At TEB, Mira faces Wagner, Sawada, Meier, Meissner and MAO Asada. This is a tougher bunch than she faced at Skate America, and in another month, they should all be in good competitive shape.
