My issue is this. A take-off of 1/2 turn or less is an acceptable takeoff. A landing of 1/4 turn or less is an acceptable landing. Giving credit for extra rotation means you may be accepting either a deficient takeoff or a deficient landing. Jumps are not supposed to be landed with more than a 1/4 turn on the ice, no matter how amazing the takeoff is. It isn't a matter of how much someone rotates in the air; just take-off properly and land properly. This is what I interpret the rules to mean, but anyone else can have their own interpretation. However, to say your interpretation is the only acceptable one (and contrary to a plain reading of the rules) and everyone who disagrees is stupid or naive is wrong.
This. Seems that one of BoP's issue with Karen's UR calls is that she doesn't pre-rotate as much as some of the other skaters. So that somehow absolves her from a UR landing because "overall" she's rotating in the air more. But, as mentioned, that doesn't matter and has no bearing on if the landing is cleanly rotated. The landing of 1/4 turn or less is acceptable. You don't get bonus points either if you have no pre-rotation or absolute full rotation on the landing (e.g. Gold in the past).
Some fans also just see what they want to see (it's unsurprising if a fan views their fave skaters as perfect technicians who can do no wrong). Kanako Murakami (who I was a fan of, mind you) is a past example where certain fans kept complaining over and over again that the judges were giving her unfair UR calls, and every time a protocol came out, it was a broken record that she was getting unfair calls. I get that tech specialists are wrong, but when a skater on a regular basis gets the same technical deductions/issues called out by different panels, whether nationally or internationally, the onus is on the skater to adapt and improve, or do
something (which I'm sure Karen is attempting to do).
Look at Mirai. She was always prone to UR calls, but she's as of late become stronger and more fit, and her jumps have more spring and tighter rotation. Her pick isn't pointing down and rotating on the ice as it used to, thanks to said height. Hence, fewer UR calls (at least as of late).
And yes, everyone is free to have their own interpretation of the rules. But it would save them stress each time a protocol comes out if they actually understood what the judges were assessing (even if they don't agree with it). Judges have never looked for pre-rotation (unless it was a super obvious toe axel). They only care about landings, not to mention, they don't have time to check pre-rotation for every skater, along with other replays.
