(It was already laughable at the last Junior Worlds: Jenni Vähämaa got a 5 something for skating skills and all three US-girls a 6 something? So Zhang got better Skating Skills than Vähämaa?

I have no problems with the overall result or the podium - but the judges could give credit where credit is due).
Just to tweak your memory----

VAHAMAA - TES: 47.08 SS: 5.89
2A, 3L+2T, 3T+3T
< df and to, 1F, 3L+2T, 3F (fall), 3S
If Vahamaa got a lower mark for skating skills, it is because she didn't attempt a lutz, didn't land a 3F, her 3/3 attempt was underrotated and she had no 3-jump combination. If her PCS scores were overall lower, it was because she had a somewhat messy skate, with a fall and some awkward landings.
Flatt and Zhang both had fully accredited 3/3s, and they were combinations with the harder jumps (lutz and flip). Each landed two lutzes, two flips and a 3-jump combination in her program. Both skated visually clean programs with no jarring landings, step outs or falls.
How about
you give credit where it is due.
