FWIW: If the technical controller does not call it UR, then the judges would have no reason to mark down Hanyu's GOE. The judges do not give or takeaway GOE based on "perception of UR" but rather based on the recommendations of the technical panel. (I do not think it was UR, IMO).
Here's the guidelines for determining +GOE. They state you should give +1 for fufilling 2 of these guidelines; +2 for fufilling 4 of these guidlines and +3 for six of those guidelines. If the tech controller calls the jump UR, judges are recommend to take out -1 or -2 GOE. However, that was not the case. So with that in mind:
Most of the judges gave +2 with two judges giving +3 (one judge gave +1) . But the majority of the judges felt he fulfilled at least 4 of the bullets.1) unexpected / creative / difficult entry
2) clear recognizable steps/free skating movements immediately preceding element
3) varied position in the air / delay in rotation
4) good height and distance
5) good extension on landing / creative exit
6) good flow from entry to exit including jump combinations / sequences
7) effortless throughout
8) element matched to the musical structure
Here's Yuzuru's program's at the point of that 3A-3T: https://www.youtube.com/watch?v=QpB5jaiA27s#t=02m58s
I'd say, that he definitely got bullet point 1,2, 7 and 8. (Difficult entry, steps, effortless and elements matched to the music.). The ones who gave +3 could make a case for point 3, 4 or 6 as well, though I think it could go either way. Point is, perhaps the combo is not the best he could do that, but GOE doesn't judge based on comparisons to the skater best attempt, but whether, in general, the jump as done that day, fulfills the requirements.
I'd say +2 is reasonable. I think the guys that gave +3 were a bit GOE happy.
