Left arm rotates according to the rhythm of the stroke, i.e. hinge action accompanied by a hands controlled pivot.
Don't fall into the position golf trap. There is rhythm and pace of the stroke. You must have both from putt to drive. You don't have to intentionally "do" a flat left wrist roll on the downstroke, but you must be aware of it and set up for it. Remember on a full stroke that the shoulder turn is rotating at least 45 degrees from the top of the stroke to impact.
When discussing turn, roll, and hinge action, Homer did say that it was "easier for him" to take the club away (turn) in the same manner he wanted it to roll on the downstroke. (my words).
All that matters is the 3/4th of an inch during impact and the smooth motion that got you through it.
Flat left wrist, smooth rhythm, straight plane line, and a planned hinge action.
Any course, any time.

My next question is when does it rotate in the backswing and forward swing?
Do you think that it is a good idea tto have them mirror the style of rotation on back and downswing?
ie. early rotation to plane / standard wrist action / swinger generally keeps clubface rotated against plane for longer time in downswing with later rotation back through square on downswing? Similar feels to hand motion...??
Having watched and rewatched "the pp3 -where R U" so many times now i have suddenly thought that the timing of the of the downswing rotation of sweetspot from against the plane(open face to target line) back to approaching square for impact is governed by who long into the downswing your hands maintain pps quarter turn rotation lag sensation.
Keep pp3 on top of the shaft for a longer time in downswing and you delay your accumulator 3 rotation??
is that right?
Is that useful ?... it sounds like a good thing for max speed...
is this how one controls the degree of overlap of accumulator release in sequential swingers style release??
Is there a relation to how long pp3 rstays quarter turn rotated and:-
-delivery path of hands
-timing of plane shifts in downswing
-pivot
- degree of overlap in sequential release (6-M-1)...
6-M-1. DOWNSTROKE SEQUENCE
The Downstroke sequence of the Stroke Components is dictated essentially by Centrifugal Force; "Over¬taking" by a lagging Component ends at the instant it achieves an "In¬Line" position with its immediately preceding Component.
Centers and Accumulators can be sequenced, overlapped, omitted, em¬phasized, triggered, and timed as the player's understanding and skill permit; But the Club's Swing Radius (6-B-0) ends at the "non-lagging" Component nearest to the Clubhead. The "Centers" of the Stroke start with the Feet or the employed Component nearest to the feet in the fol¬lowing order: Knees, Hips, Shoulders, Arms, Right Elbow, Left Wristcock and/or Left Hand rotation. For maximum Power, the position must be taken that will allow Delay of the Release until all Components, except the Right Foot and the Right Shoulder, have reached, or passed, the Line-of-Sight-to-the-Ball, per 6-B-1-C. Then the Accumulators must move very rapidly toward their "In-Line" Position. None should actually arrive (lose all their Lag and Drag) until well after Impact. (See 6-H-0.)
Power Accumulator Release sequence is #4, #1, #2, #3 - regardless of which ones are being employed. Any Accumulator number may overlap or replace its preceding number but cannot precede it. Increase Overlap to increase Thrust - decrease Overlap to increase Velocity.
i am sure there is some connection between al these aspects... just not sure yet... any guidance please?

Does the left arm rotate on the backswing? If it does how much?
Mine doesn't for putting, chipping (angled hinge for both) and pitching (vertical hinge).
Mine does in shots using horizontal hinge. That's how the club(head) can be kept on plane.
How much? I have no idea, as long as it's on plane, assuming the left (lead) arm is straight. In other words, the "law" does it for you. Actually, it also automatically does the right arm fold, left wrist cock and right wrist bent.
__________________ Yani Tseng, Go! Go! Go! Yani Tseng Did It Again! YOU load and sustain the "LAG", during which the "LAW" releases it, ideally beyond impact.
"Sustain (Yang/陽) the lag (Yin/陰)" is "the unification of Ying and Yang" (陰陽合一).
The "LAW" creates the "effect", which is the "motion" or "feel", with the "cause", which is the "intent" or "command".
"Lag" is the secret of golf, passion is the secret of life.
Think as a golfer, execute like a robot.
Rotate, twist, spin, turn. Bend the shaft.
The local rotation of the left arm relative to itself is dynamic in terms of degrees which changes as the shoulder motions displaces it and however it raises upwards in relation to the plane angle variation you wish to use. Its 'turned' state however, always maintains a constant relationship to the straight plane line.
Mine doesn't for putting, chipping (angled hinge for both) and pitching (vertical hinge).
Calling Annikan Skywalker,
I believe the left arm connects to the shoulder by a "ball in socket" joint because of this any motion of the left arm back and through will have external and internal rotation (not always in that order) whether you are tracing a straight line or not. The amount of rotation may be very small but there will be some.
I will wait for someone with a much better understanding of biomechanics than I to post and confirm or deny my conclusion above.

The shoulder is a ball and socket joint, but it's held together and supported by soft tissue, not the ball and socket structure itself. Because of this, it is the most freely movable joint in the body. The movement of the left arm back and through, and the rotation of the arm, are independent of each other. So the arm dosen't necessarily have to rotate as the arm moves back and through; those two movements need to be coordinated.
That said, I think that it is probably unlikely that the arm wouldn't rotate to some degree, due to the movement of the club during the swing, unless the player does something (either intentionally or through poor mechanics) to prevent it.
Very interesting post about the soft tissue......and the fact that the shoulder is the most freely movable joint in the body. I learned something today......where do you get your biomechanics information from I would love to learn more. I still have a hard time believing though that the left arm can truly move straight back with a club in hand.....maybe in theory it can move straight but I have a hard time believing this is what it's actually doing.

I get my info mainly from my education. I'm training to be an x-ray tech, so I have to know that junk . I agree with you about the arm moving back without rotation. Like I said before, unless someone does something, maybe intentionally or through bad swing mechanics, it's not likely that their arm will move back without rotation; the golf club dosen't want to swing that way. And it isn't too comfortable, either.

Do something for me everybody:
Pretend you are holding a comb or brush. Now begin to style your hair. Assuming you have some, of course; otherwise, pretend you are a stylist working with a customer.
Imagine you are looking into a mirror and comb away: the front, the sides, the back, all 'round. Use the other hand to help the 'smoothing' process. Note...
1. The hand only holds the comb or brush.
2. The forearms rotate naturally, as they should.
3. You don't think a thing about it.
So it should be during the Golf Stroke.
Unfortunately, many people do strange and unnatural things with their arms and hands and bodies during the Stroke. Usually, these contortions are the result of incorrect concepts. Only when the correct concepts have been learned and applied will the corresponding motions be brought to their natural state.
And only then will you begin to play your best golf.
