How

Like I said, all the correct mechanics are readily available to anyone. As much as I despise the teaching styles of people like McLean, Leadbetter, Rick Martino, and Martin Hall, and think they focus far too much on symptoms instead of causes, I don't dispute that there is anything wrong with the positions they advocate. Once you can "feel" those positions, along with rhythm and tempo, you can accomplish the mechanics easily.

It's like my example of all the people at the range who know the correct positions because I see them practicing putting themselves into those positions. They've been to the teachers, they've read the books. But they can't "feel" to dynamically reach those same positions. It's not a lack of mechanical knowledge.
