Why not have all judging panels selected like this? I'd love to see 6 people chosen at random judging the dressage based entirely on whatever they happen think dressage should be judged on. And at the same times the riders are trying to alter their routine based on what they think someone who knows nothing about dressage would want to see in a dressage competition.
Yes, why wouldn't those that trained some disciplines for years want to have their fate decided by complete randoms with no judging experience in their sport!?
