Our course has 2 settings for the turn buoys. We have an actual setting that was used when the course was surveyed, but we also have an inside setting which is 4.5" narrower than the actual setting. It's still within tolerance and would pass any tournament inspection. The idea is to put the buoys on the narrower setting in the spring, to avoid handle/ski throws and yelling at the driver, and then move to the actual settings in the summer and fall when the elements are a little more cooperative.
The difference between the two settings for an elite skier, one who is looking to run 39 every round and have a crack at 41, is absolutely ridiculous. It takes a 2 to 3 at 41 off skier, and turns them into a 4,5 and 6 at 41 off skier. You throw in a rope that is 3" longer than actual and on top of that you get a driver who is 2" on your side at most of the buoys(all within tolerances) and you've got quite an advantage over a different ski site that has their buoys on actual settings, actual ropes and super tight driving. Even for 35 and 38 off skiers the advantage is huge.
I'm not saying this is what happened in Spain at all, but I think what @Horton is saying is that there has to be a specific set of reasons why some scores at some sites get inflated, other than everyone was pumped up and feeding off of everyone else. Even if the reasons are legitimate and merely just pushing boundaries, it's tough to compare those scores to scores from tourney's where everything is super tight. We took away the ability to give the skier a 16.28 with speed control and everybody is on the same page with that. I would be very surprised if everybody was on the same page with course, rope and driving dimensions.
