The data does not conclude that at all, that is your own seems as if idea. The hands cancertainly go a constant speed through release and all players should strive for it. Set the initial thrust so the hands can move at a controlled speed and uncock and roll and release

You're not reading the data correctly.

All players should strive for lagged accumulators and not think about the endless belt model.

The player should use the Thorax to drive as heavy a pressure in PP#3 as he can muster at the ball, and the hands will move at the required speed, as long as he doesn't try to add.

please explain the data and show me what it concludes or how it proves your point. the endless belt is a great way to understand the release and I know greg smith and I have discussed it many times during practice. wheres the data, what supports your point? what point do you have?

Strive for a continuous, smooth, constant hand speed throughout for all shots, from tee to green and I promise, you will be a better golfer. this is practically half the mechanics for me along with extensor, constant hand speed and extensor ARE BIG DEALS

Look at the graphs in the study! I've already discussed them above. The endless belt doesn't have an uncocking club attached to it, only a duck!

I suspect that you say this because you are a sweep releaser and that's how it feels to you. You probably have a circle hand path, which would mean you don't really have a pulley. In that case you have to feel a "smooth, constant" hand speed in order to avoid so much #2 throwaway that your hands can't get to the ball before the clubhead.

whip, you should not be aware of hand speed at all, since the necessary hand speed in a Swing is provided automatically by the pivot actuation of #4 and then #2, ideally properly sequenced and lagged. Look again at the pro graph in the Cheetham study. You want peak hip speed to precede peak thorax speed to precede peak left arm speed, which decelerates rapidly before impact. To get this, you drive the right shoulder while keeping #4 fully loaded, so it can "blast off".

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.

As far as you telling me that my notions are derived from my own procedure that you viewed on YouTube I'll refer u to this post by the late great Matthew

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!

angular velocity
 

I have noticed that the "measurement" show NO interaction or disruption of the angular velocity curves between adjacent elements.

Specific- the thorax/arm curves for the pro but likely disruption for the amatures. "IF" #4 is "thrown off the chest" I would expect to see it in the pro curves. I have had some ideas on this subject but first I would like to hear your opinions.

HB

To blast off or pack ?
 

Interesting. And how does Blast Off jive with Rhythm?

What ya got Bear?

The arm NEVER "touches" the chest!???

HB

Interesting. You got your "plugged in" types. You got your "blast off " guys ... and I guess you got your 'NEVER touches " . Different strokes for different folks... OK by me.
