Agree with you. But I think everyone should go through what you call Stage 3. Otherwise Stage 4 is an impossibility. I hope I'm in Stage 4 already. Sure trust my teacher, and I think I understand him completely. Matter of fact, makes studying the gokf swing boring now...I should play more. If only I don't have a day job...Tying shoelaces is a simple task (Stage 4). Learning to tie them from scratch is not so simple (Stages 1, 2 & 3) . Consciously explaining what you are doing when tying them is also very difficult (a Stage 4 unconscious competence explaining the task consciously, Stage 3)
