Geometry of the circle and how it applies to shot shaping .

Can't assume that!

Can you have poor Rhythm and a Flat Left Wrist? We must at odds with our definitions . Not uncommon.

There are 2 parts to HK's rhythm. The same RPM for BOTH lever assemblies- That is the flat wrist piece. The second is a steady/even (smooth) overtaking rate. I believe it is possible to have either, both or neither, and the second, overtaking rate, can have a "broad" range.

But if you had a flat left wrist would not the entire Primary Lever club head, hands, arms be travelling at the same RPM about the Primary Lever's centre? Isnt that Rhythm , capital R by definition?

That is 1/2. The smooth overtaking rate (I said can be very broad) is the other half of rhythm.

Example-a smooth flippy swing may be good part 2, a hip or elbow stall making a "jerky" motion with flat left wrist is only part one.

Not articulate but done.

As an aside.

Re the clubhead "overtaking" the hands with Rhythm (flat left wrist) assumed. IMO a key key concept for the guy on the tee. With a flat left wrist the entire left arm and club , (the Primary Lever) moves as one, rolls as one. The clubhead, the hands the left arm have the same RPM but different surface speeds given their distance from the centre of their motion, the left shoulder.

From the caddy view the clubhead passes the hands (somewhere around or after impact, depending). From the players point of view the clubhead passes the hands. But imagine a camera attached to the left shoulder which looks directly down the inline left arm and club and rolls with the Primary Lever as it rolls....... this camera would not see the clubhead as passing the hands!!!! If you played its video back you would see the whole world spinning around the inline Primary Lever .... inline Left Arm , Left Hand , shaft and clubhead. The world overtaking the intact Primary Lever if you will.


Break the left wrist and the clubhead does pass the hands , from any perspective. My grandfather used say " Well, it all depends where you're standing when your pictures took!".

It is important to know (for me) Is the camera a vertical camera for all hinges or is the camera attached to the hinge pin?
The results, to me, will be VERY different for each hinge action.

This Rhythm question may expand your circle geometry thread because it is part of the circle geometry but the "startionary "head"" [more
so] and Balance [less so] are also part of the geometry so I use caution.

Camera attached to upper most part of left arm under the hinge so to speak.
