Well, Hanca, apparently the judges don't agree with you.
When Liza was a junior, her ice coverage was tiny even for a junior. Her coverage may be somewhat better now than it was back then, but she is skating senior now, and her ice coverage isn't what it should be at this level. That affects her SS score, and in turn all her PCS scores.
"Normal, average jumps" don't get high GOE---average is 0 GOE. Liza doesn't get much flowout on her jumps (part of her coverage problem) and that also keeps GOE low.
Well, I think the judges actually agree with me. Liza wasn't marked that low at Europeans! I agree that at worlds she had a bad competition, but if you look at her results throughout the last year, I think she is doing pretty well. Second year in row getting into GPF, winning the long program at Europeans (beating Carolina Kostner), finishing third at Europeans, what more would you expect from someone first season fully senior? Her personal best (and season best) is 188.85! Not bad at all!
