Consider this AMG swing video where they discuss the driver golf swing action.
The AMG instructors discuss the "release of the club" (starting at the 9:40 minute time point of the video), which they do not precisely define - but they seem to imply that it involves the club catching up the to the hands by impact and where the clubface is square at impact. With respect to TGM terminology, that would represent the release of PA#2 and PA#3.
However, when they discuss how to perform, and monitor the effectiveness of the "release action" (involving the sequential release of PA#2 => PA#3), they only talk about the trail arm (and not the lead arm) and they only discuss how a golfer should "feel" that the trail hand is "shaking hands with the target".
It puzzles me that they do not discuss the actual biomechanical/mechanical factors responsible for the efficient release of PA#2 => PA#3 in a pro-quality driver golf swing action. How can they simplistically believe that getting the trail arm to fully straighten after impact so that the trail hand can "shake hands with the target" is the most effective method of teaching a student-golfer how to efficiently release the club into impact, and through impact!!!
The AMG instructors have a world-class teaching facility with all the latest tech equipment (eg. force-plate measurements, GEARS 3-D system, launch monitors) and yet they fail to discuss any of the relevant biomechanical/mechanical factors involved in the release of PA#2 => PA#3.

Consider Andy Carter's opinions on the "release". Note that he does not separate the phenomenon of the PA#2 release action from the PA#3 release action or from the post-impact hand release action. He basically believes in the 9-to-3 drill where the clubface rotates 180 degrees between P6 => P8 and where the roll motion due to a PA#3 release action flows non-stop into a rolling subtype of hand release action. He states that he cannot explain when to initiate the release or how to control the timing of the release and he simply hopes that the clubface will be square at impact - based on the timing of the arm motion across the body which is simultaneously rotating.

Here is Clay Ballard expressing his opinions on when to properly release the club.
He is obviously referring to the release of PA#2 because he starts at ~P6 with a ~90 clubhead lag angle, which then disappears by ~P7.4 when the clubshaft is angled ~45 degrees to the left (that he calls a "straight line release", which he defines as the butt end of the clubshaft pointing at the center of the upper chest).
He does not explain why the endpoint of the release is defined in the manner that he defines (= straight line release) and most importantly he does not really discuss when to start the release of PA#2 (which usually starts between P5.2 = P5.5 in most pro golfers).

Here is Mark Crossfield expressing his opinions on the release.
MC does not even discuss the pre-impact time period when PA#2 and PA#3 are sequentially released and he only states that one should end up in the later followthrough (after P9) with the butt end of the club pointing at the target. He seems to imply that it will guarantee a square clubface at impact.
Here is another crazily-stupid MC video on the "release"
MC states that one should try to determine the relationship of the butt end of the clubshaft relative to the trail forearm after impact. He states that a "complete" release will cause the butt end of the club to be angled behind the trail forearm while a "hold-off" release is when the butt end of the club points ahead of the trail forearm in the early followthrough. He thinks that a neutral release is when the clubshaft is straight-line-aligned with the trail forearm in the early followthrough.
I do not think that his "idea" represents a crazily simple "idea" and I think that it represents a crazily stupid "idea".

Here is Kerrod Gray giving advise on the "release".
He uses an endpoint when the trail arm is parallel to the ground - because it is an easy endpoint to measure.
KG states it is difficult to measure what is happening to the club through impact, so her prefers using his specific endpoint measurement.
Phew!
The state of the world of online golf instruction is in a "very poor" state if this video is supposed to represent useful golf instructional advice!

Here is a video by A Davies talking about the best way to release the club.
Note that he talks about the lead arm motion through impact and he simply wants a golfer to ingrain the "feel" of the watchface area of the lead lower forearm rotating through impact.
That's it!
He actually believes that a rolling subtype of hand release action through impact controls the clubhead path and the clubface alignment at the same time.

Here is Milo Lines talking about the perfect release pattern.
He states that the perfect way to release the club is to square the clubface (relative to the clubhead path) by ~P6-P6.2 and to then keep the clubface square throughout the remainder of the late downswing into the early followthrough.
I think that Milo's golf instructional advice stems from his personal use of a very strong lead hand grip where he does not "feel" the roll motion of a PA#3 release action. That advice cannot possibly be relevant for a pro golfer who uses a weak-or-neutral lead hand grip.

Dr Mann
It seems there is no agreed definition of release in the golfing fraternity and even the golf scientists have differences.
Some people regard release as a 'process' which, in itself, can be defined differently.
Others define release as a point in time which again can also be defined differently.

Dr Mann It seems there is no agreed definition of release in the golfing fraternity and even the golf scientists have differences. Some people regard release as a 'process' which, in itself, can be defined differently. Others define release as a point in time which again can also be defined differently. DG True! However, they would seemingly all agree that the "release" at least does involve getting rid of most of the clubhead lag that allows the clubhead to reach impact when the hands reach impact (= PA#2 release action) and that it also involves squaring of the clubface by impact (=PA#3 release action). Despite the above "facts" they do not discuss the biomechanics/mechanics involved in the release of PA#2 and PA#3 - which is what student-golfers specifically need to learn. Some golf instructors also do not clearly realize that the pre-impact PA#2/PA#3 release action and the post-impact pattern of hand release action (DH versus non-DH) are not a single "releasing process" and that different combinations can exist.
