To me, under-rotation is cheating and does not show real athleticism. I never liked how Sarah Hughes cheated her jumps. It’s like in a 10,000 m running event, your rivals run 25 laps but you only run 24 laps. That’s cheating. If your rivals can rotate their jumps but you cannot, then you should not get same points as your rivals on those jumps. Otherwise it’s not fair.
Plus, I don’t think we need to look at the protocols to tell if the jumps are under-rotated or there was a wrong edge takeoff. Many times I watch the replay and immediately know that it’s a URed jump. I know some people don’t like falls, some don’t like popped jumps, others can’t stand terrible skating skills, etc. I think all these mistakes should be punished, including UR and wrong edge takeoff. JMO.
