You are correct for the plus GoEs that is one reason, I would eliminate them from scoring, however the minus GoEs can be quantified beause the skater did not reach the level of a Base Value, and should be penalized. Skaters who add something innovative after earning the Base Value, should be scored in the PC scoring where opinions rule the whole CoP system.
After all the hullabaloo about CoP scoring as not being based on opinions, we are now talking about it's impossible not to opine in a judged sport. But can't we at least leave the opinions out of the Technical? That would be more sporty
This is interesting but I think there has to be +GOE. If there wasn't, then the quality of elements wouldn't be as important. A very large Triple Lutz should score higher than a small Triple Lutz.
You're suggesting that big jumps should be awarded in the PCS, but big jumps do not necessarily reflect great skating skills or performance or interpretation...
Opinions on the tech has to be part of it. Other sports that are related to jumping have it as well. Diving and Skiing Aerials both require judges to have an opinion on the landing, and of course there is Gymnastics...
