Sorry to gravedig a bit, but I've got a bit of a story to tell. Shockingly enough, this tactic actually works. I was just out training with some friends. One of them could not do a kong to precision. He tried once and screwed up his foot a little. Trying to convince him to do it again, since I knew he could make it, I told him about this thread. To my surprise, he tried it, and landed the kong to precision. To sum it up, it was amazing.
