I think this is a good idea, but going back to Sochi (and again I don't know what you want to rescore here), I think TP for Spin and StSq levels is a good idea, because I think Yuna's StSq levels were called incorrectly. At least in the LP.
But what standard of judging? IN and PE are at least a little subjective. Going to Patrick Chan's SP in CoC 2016, would we have someone give him anything more than a 6 for IN and PE? OTOH, a skater having a meltdown doesn't necessarily have to be performing too badly, like Boyang in his SA 2016 SP, who would be getting a 7 for PE there from me. Would the judges necessarily evaluate everything properly without standards for PCS? For instance, I don't think Seimei's CO in 2018 was a 10 (close to 9), but is there a standard there?
