The tech panel has access to video replays that you or I can't see, and they are trained for this. They're not always right, but it's ridiculous to automatically dismiss them when they don't give the scores we expect (read: want) them to give. I thought Vincent's jumps were fine. You didn't. The tech panel thought they were clean, and have been marking skaters for URs so far in this segment. They must have considered his quads sufficiently rotated even if others didn't.
Note that if a jump is to be considered under rotated by the tech panel it must me a quater or more left. A jump that has 10-5minutes left is in my opinion still UR but isnt called due to the current rules
