Dr Mann
With reference to this video below , can I assume that Monte Scheinblum is advocating a 'No-Roll hand release action' with a 'CP arm release'? Where he is using his pelvis/upper torso as an active pivot through the general impact zone (with no independent roll of his left humerus/forearm) to square the clubface?
What I don't understand is why he is advocating a 'sweep' release of PA4 , the left upper arm separating from the chest almost immediately after P4, because wouldn't that make it more likely to have a disconnection between upper arms/torso and independent roll of the left humerus/forearm to square the clubface?
He is very vague from 8:16 onwards where he says " as you shift, you accelerate the left arm off the chest " (release of PA4) but he doesn't explain how he does that . I am assuming he is using his left shoulder girdle muscles because he mentions Justin Rose is "very big on keeping his chest closed and bringing his arms to here and then pivoting". That he is using the left arm (like Leslie King swing technique) to release PA4 . It seem almost as if he advocating a 'reactive pivot' from P4-P6 , then an 'active pivot' from P6-P8. Am I correct?
Further ,if I have correctly interpreted what you have written in your 'Hand Release Actions Through the Impact Zone' chapter, wouldn't a golfer "need the requisite amount of torso flexibility and physical training to perform this action fluidly and efficiently."?

DG I think that it is a waste of time listening to MS. One cannot square the clubface via body rotation and without a PA#3 release action. There is no such entity as a sweep release of PA#4, and there is only a sweep release of PA#2 (which is primarily due to premature right arm straightening). MS states that the left arm should move away from the torso before the torso rotates. That does not happen in a pivot-driven swing (which is the swing technique used by most pro golfers). Here is Jamie Sadlowski's PA#4 release pattern. Image 1 is at P4 - I have placed a green ring over his left shoulder socket.
Image 2 is at P4.5 - I have placed a yellow ring over his left shoulder socket. Note how much his left shoulder socket is moving between P4 and P4.5 and it is pulling the left arm downwards.
Image 3 is at P5. I have placed a blue ring over his left shoulder socket to show much it has moved between P4 and P5. It is simultaneously pulling his left arm downwards - assisted by an active right arm adduction maneuver, which can result in increased push-pressure being exerted at PP#1 by the right palm.
Note how much the upper torso has rotated between P4 and P5 while the left hand is being depressed (moved groundwards) from being high above his head at P4 to being at shoulder level at P5. The reality is that i) upper torso rotation and the downwards motion of the left arm (representing the release of PA#4) happen simultaneously in an active pivot-driven golf swing. The same phenomenon happens in Justin Rose's golf swing. Also, the pelvis is rotating actively between P4 and P5 and they (JS and JR) do not only pivot between P6 and P7.
Here is Jamie Sadlowski's 3-D graph showing that the pelvis rotates first - before the upper torso - which means that he has an active pelvic rotary action that starts in the late backswing and continues throughout the early downswing at a speed that is faster than the speed of upper torso rotation.
I don't see MS talking about a no-roll hand release action in this video. Jeff.

Many thanks for that explanation Dr Mann.
Also thanks for correcting me about 'sweep release' although I'm still a bit confused about the difference between a sweep release and casting?
Definition Casting: "Casting in the term used to describe the phenomenon whereby the maximum degree of lag angle is lost in the early downswing"
Are these definitions accurate for release phases of PA2?
Sweep Release: A club release between 4.5 and 5.25 -using a passive CF release
Random Release: A club release (PA#2 release) action that happens between P5.25 and P6 - passive CF release
Late /Snap Release : Happening in the early phase of the late downswing (or even later for snap release) , after P6 . Not using a passive CF induced release.
Thanks DG

Not using a passive CF induced release. Thanks DG I do not have a precise definition that differentiates casting from a sweep release, which happens before P5.3 - although I tend to think of casting as being a swing fault while a sweep release is not a swing fault, but the result of a circular hand arc path starting in the early downswing that has the capability to cause the release of PA#2. A random release happens between P5.3 and ~P6 (arbitrary endpoint choice rather than a scientifically sound choice) and a late release happens after ~P6. However, I am still inexact in defining when a random release becomes a late release because I do not see any late releases in PGA tour golfers. Do you know of an example? I have habitually used the TGM terms "sweep" and "random", but I have never seen those TGM terms defined in a precise manner. Jeff.

Richie Hunt's opinions re: TGM are inaccurate and worthless! Jeff.
