starting down for swingers

[JulesC]

Hi folks,
My first post. I am a serious low handicap golfer finally looking to take my game to the next level and get back to being a competitive golfer. i have had lots of lessons from distinguished teachers but only recently have found my way working with an authorized Golfing Machine instructor. I do have one question about which I am not sure I have found an answer. From the top/end to start the downswing as a swinger I of course bump the left hip and sit down and tilt simultaneously. I don't do anything with my arms. My right shoulder drops on plane and begins to point along the plane line. so far so good. What I don't get is the connection between this 'move' which seems right and two other ideas that don't seem compatible with it. The first is the idea of a quick move to start the downswing which appears both in TGM and in Lynn Blake's video. The second and related idea is that the right shoulder creates a flywheel movement which helps the inert left arm separate from PP#4 and releases the associated power accumulator. I think of a flywheel as an outward motion, yet the right shoulder motion i am taught is both slow and down. I need some clarification including whether these two conceptions which seem conflicting to me are in fact compatible.

Thanks,
Jules
