Yea, I agree that the judging was a bit iffy, but that's the problem with judging a subjective/style based competition—how do you quantify style, and/or apples to oranges?
I think Simon probably should have earned the win, but Jossi's run was stomped and certainly arguably deserving. But, I also agree that Simon's reaction was lame. Sure, he has every right to be disappointed and he IS a competitor and I think genuine disappointment is better than feigning excitement for Jossi, but he would be a lot more likable if he figured out how to be honest in a more tactful/tasteful way.
As far as Peter's, well, I think he should have scored about a full point higher... that said, I don't think his run stacked up to either Jossi's or Simon's. Sure, his alleyoop dub flat was the tits, but he lacked the amplitude, style, and landings of those two throughout the rest of his run. Props to him for getting back on the podium after struggling for over a year. I know I personally wrote him off as a potential threat in pipe last year.
One other thing:
I think transition riding plays a way bigger role in scoring than many think. For example, Simon and Jossi both land at the very top of the tranny, skis pointed right where they need to be, whereas Pete slid/scrubbed/underrotated a few landings. Jossi, in particular, has such a quiet upper body upon landing and pumping in between hits...it looks so much more controlled and fluid, and I think that boosted his score. And, it should in my opinion.
