As I had predicted - and as some people had ignored - earlier in the season, Karen's jumps aren't in great shape, currently, and are prone to UR calls and hooked landings. Continually claiming that her jumps are sufficiently rotated and hoping for tech panels to agree with you isn't going to help her.
She isn't more prone to underrotation than most any other lady out there. Her jumps did not deserve most of those calls at JO and anyone can check the video for themselves and look, rather than blindly trying to make blanket statements and act like the caller was correct, as you always do. Her 3Lutz+3Toe was superb, and her 3Flip, 3Sal, and 3Loop were all fine. She had a jiggle and noticeable turn on the landing of her 3Flip, also a noticeable turn on the 3Loop (and a little bit on the 3Sal), so of course a caller who doesn't know what they are doing just calls it underrotated because they don't understand what they are looking at and how to measure the rotation.
The uneducated caller just sees the blade turning on the ice, or some kind of other visual "flag", and makes a call without paying attention to where the jump started, like on her 3Loop where it would be considered underrotated if she had started the jump (and taken off) going towards the side board of the rink, but in fact she started the jump traveling diagonally across the ice and thus from that direction it can be seen her landing is within 1/4 of a turn.
Talking about her jump technique and factually assessing them does indeed help her and it's exactly what the U.S. Fed needs to be doing on her part. The calls that get made at the Olympics will be because of the understandings put forth prior to the performances, and the reputation and politics. Yes obviously the totally unquestionable calls will always get made (well, most of the time...), but all of the grey areas are where the decisions can vary to a wide extent and will be decided by how much the ISU understands and cares to reward the skater/team who is being judged.
