Joe I use random sweep, have never sweep released nor am I concerned with what it feels like to me to explain the physics, you say that a sweep release has no pulley this is incorrect the pulley is just larger than a snap release pulley. What you don't seem to understand is that in a sequenced release the number four must be released prior to #2 if u delay four until the last second releasing two and four at once this is not a sequenced release. I don't care for thT particular study and you still have not explained anywhere why the more #2 you have the more u must slow down the hands or how these graphs show that and I would highly question this data anyway. Constant hand speed is a virtue I'll say it again and again, and work on it constantly in practice along with extensor, they are the backbones to a smooth consistent structured motion. If u have a book, an look at the endless belt it in fact DOES have an uncocking club attached, grizzly Adams did have a beard! In a swing we are not driving the right shoulder the hips via the axis tilt pull the shoulder down plane which in turn throws the number four off the chest, then the number 2 uncocks and the number three rolls. If u realize what ur typing ur telling golfers to rapidly decelerate their arms and not be concerned with a constant hand speed, this is disastorous.

Oh boy!

Yes whip, in fact I do understand a sequenced release. But, the release of #4 happens as a blast off from the shoulder drive, and it happens late, but WAY before #2 in a snap release, whereas, a sweeper, random or full, lets the motion of #4 trigger #2 release with the club head moving backwards too early. This makes the #2 and #4 releases too close together.

If you aren't driving that right shoulder, you are using only hip pivot and tilt, which is anemic in comparison.

Gee whip, you really haven't been reading my posts. The player doesn't decelerate the left arm, the physics of a proper pivot driven Swing does it for him!
