This thread contains large amounts of ignorance concerning judging.
For the snowboard part it's simple: Hands down in the landing, points deducted. That's why Ståle didn't win.
For the skiing, it's also quite simple: The judges don't give a fuck about what you think is boring or repetitive, they judge based on execution and difficulty, which is why Henrik won. However, judging has a subjective element to it, which is probably why Kai got 2nd. I don't think judges do it consciously, but it happens.
The OP is really just plain stupid, and I guess the Kentworthy thing kind of underlined that.
