Shhhh. Don't tell. I think Louie just made it up.
I'm sort of not kidding. He seems to have such a clear training philosophy that I almost wonder if he "knew" how to put a system together and then went looking for evidence. The rate at which he refines his system on an intuitive level is incredible, I doubt he'd let the Text get in the way of a good idea. But you've met him, what do you think?
