I don't think there's any conspiracy either, but the posters who have suggested that judges may be influenced by crowd reactions may have a point. They're human and they'll never be completely objective, and things like the mood and atmosphere in the building have to affect their perceptions to some extent. And I've been to competitions here in Canada; Canadian crowds can really get wildly enthused about cheering on "their" skaters, perhaps more so than other countries. I remember attending Skate Canada way back in 1996, and pretty much any Canadian skater who didn't fall multiple times got at least a partial standing ovation. When a Canadian actually goes out there and gives a medal-worthy performance, they go nuts. Don't know if that's changed since then (I haven't attended a live competition in a while) but it could be a factor.
They may still be influenced by skating order also, even though they really shouldn't be. I hate that.
