Setting up slighty open and then resisting the turn with your left side is a big part of it too. Then you take the club inside ala Elk and then roll it to the top trying to get your right arm in that position on the video. Downswing is about lag created by your right shoulder turning thru high and ahead of your hands until impact when the smash happens. Thats my take, I think I understand it but as a once a week golfer who might hit 1 bucket a week as well I can't do it, I will continue to try to do it primarily because I have met Martin and had the clinic with him and have seen how he hits the ball using this method.
