Awesome......I've been interested in your take on this for quite a while.....even though for all intents and purposes I have given up on trying to "reduce closure" and have found the pursuit basically pointless, I was still intellectually curious about what this machine would find. I'm sure the haters wont be satisfied with your experiment, but I trust that you did this adequately. I'm sure there'll be more good stuff to come. :)

Brian is this solely due to applying force about the coupling point slows down hand speed?

Awesome, and quite simply, ground breaking.

Using science to shine a beacon at the path to progress instead of stumbling around in the dark helps us tremendously.

Thank you for your pioneering work.

Brian, your ENSO test numbers confirm:

1. If you drag the handle by maintaining a flat left wrist, you are simply defeating the flow of kinetic energy into the club. By fully releasing the left wrist and allowing it to freewheel, the kinetic energy will flow unimpeded and result in higher swing speeds. Plain and simple.

Also, according to mandrin, Nesbit, others, you cannot speed up the club by applying torque to the handle with your hands in final release. Release means "freewheeling"... and the kinetic energy is what you generate from your legs, hips, torso and shoulders ... the power segments. Attempting to torque your arms from your shoulder sockets or manipulate the handle with your hands is somewhat futile.

2. This "rate of closure" of the clubhead toe concept has always been dubious in my mind and now the numbers confirm that. The clubhead rotates around it's CofG as defined by the longitudinal gravitational axis (hanging the club from the butt and rotating it around the axis outside of the shaft) as it approaches impact.

IOW, the toe is rotating closed while the heel is rotating open around that open axis, during the downswing. The clubhead does not rotate around the shaft axis... the shaft axis rotates with the heel of the clubhead!!! (It's also possible to eliminate closure by going square-to-square as Brian demonstrated.)

If you impact on the sweet spot, the rate of closure is negated because the impact with the ball will stabilize the clubface during the momentum exchange. If this didn't happen, the ball would always go left due to the closure/opening rotation of the clubhead around the sweet spot axis! That's my take on rate of closure and impact.

The only way you can "crack the whip" is to fully release so that the kinetic energy flows to the clubhead.

Yup, and that shows up on Miura's diagrams here:

Keep on plugging the "scientific" puzzle, Brian... because we need a comprehensive, science-based golfswing theory that can be used to teach and from which to learn... instead of trying to blindly feeel your way through a homemade swing by trial and error and error and error, until it's too late to change.

Just for clarification....this "rate of closure" number (trust me, ENSO calls it something else) is at the INSTANT of IMPACT.

NOT during the impact interval!!!

So does that mean if you want more club head speed your efforts have to be applied at or before waist high?

I bet that you can add speed with your hands to start that release and that it is the last place you can add speed is with your hands.

Nobody's teaching a prominent, conscious rolling of the clubface open on the backswing and closing on the downswing? This was the standard method that the Scottish pros brought with them to America in the late 1800's. And, this is THE hallmark of AJ Bonar's teaching. He was teaching it 20 years ago when he taught me, and he introduced it to the masses with his video "The Truth About Golf".

There are 2 ensos up and runining....fujikura and ping

SteveT....club acts like a center shafted putter around impact because of lead and droop....as toe sppeds up the heel slows down

Thanks.... good point... I was thinking "static", while the "dynamic" state with the drooping clubhead will align the clubhead CofM with the shaft axis and is the correct analysis. However, at impact, the clubhead acts independent of the flexing shaft so that the shaft axis is cancelled out... theoretically.

As for the toe speeding up and the heel slowing down, that would only happen if the clubhead CofM is biased towards the heel. If it were like a "center-shafted" putter, the toe and heel would be rotating equally... with the toe closing on the ball and the heel retreating from the ball, just before impact... I think ....:confused:

When I go golfing, I don't think about all this scientific sh!t... I just go with what I got and enjoy the walk in the park.
