Right. I don't honestly understand any justification for the "defenses" described (at various websites). If the polygraph just doesn't work, why attempt any "countermeasures". The whole thing is kind of funny.

I think you're exactly right. The fact that the "butt pad" is there means that you have to believe that clinching would have any effect one way or the other. So the butt pad is really just part of the overage mirage.
