I think it's foolish to let the split panel judges focus on one PCS category each, if that's an idea being floated around. Skating Skills and Transitions are pretty intermingled, and then Transitions and Composition could be related. And Performance and Interpretation are related. And Interpretation and Composition are related. And Composition and Skating Skills can be related.
Looking at exactly one category is silly, as is hyper-focus on the "criteria" of these categories. I think splitting TES vs PCS is enough. And I don't particularly think the criteria have any use with the vague language they use, and there's inherent ambiguity between scores like "9.25" and "9.50" (there's no real feedback there, and a judge will only ever use it as a way to rank by preference - no criteria can dictate this objectively).
Funnily, if I remember last time, one of the reasons for the split being rejected was "there was too little to do"? Which one is it? You're too busy marking by the criteria, or is there too little to do?
