I've watched three JGPs this season, in whole or mostly part, and the judging has been pretty spot on so far. You might quibble about some of the points here and there on PCS/GOE but the placements have been pretty much spot on.
ssfww? ssffww? You ok? I think ssffww fainted!
I've only watched a few JGP performances, but not a whole competition. But your post prompted me to try and remember when the last competition was that I thought the outcome was completely unjustified.
And I really can't think of one. People squabble over a point or two of PCS and whether a jump was truly rotated or not... but on the whole, I think the judging has been pretty on point for the past couple of years.
Oh, sure, I might disagree that the placements are exactly where I'd have put them, and whether a skater really merits the love (or disdain) they get from the judges... but that's all opinion-based. I don't recall the last time someone REALLY and GLARINGLY got hosed by the judges in the final result.
