The left arm does rotate on the backswing while staying striaght via extensore action. So the rotation is occuring from the shoulder joint. The amount of rotation being used varies upong the destination of the backswing, it can also vary due to the hinge action that is going to be used, angeled, horizontal, or vertical, and finally it can vary due to the approach procedure and delivery paths.
These are just a few of The Golfing Machine Principles that can affect the amount of left arm rotation. I'm sure there are more and I look forward to others posts in this thread.

Does the left arm rotate on the backswing? If it does how much?
A swinger's startup swivel is a 'true rotation', 90 degrees 'turn' back, 180 degrees 'roll' through. It is important to keep in mind that this is a sequenced release, uncocking the left wrist THEN rolling. It is the pivot and the straightening right arm that imparts the 'roll' through.
A hitter would in many respects look like rotation, but the power package alignments are simply staying in their relative positions so any visual appearance of turn/roll is that of the entire power package, and not the lead forearm.

My next question is when does it rotate in the backswing and forward swing?
This is why Homer Kelley wants the hands to be Educated. The Hands control the whole Enchilada.
You can turn (to the right clockwise) the hands on plane early- from the address position as the first move. This fans the clubface open as the hands continue the back stroke. You can take the back square for foot or so and then turn them on plane. Either way this is called Standard Hand Action. A turn to the right and a roll (to the left counterclock wise) back to the left.
** see note
The second way is called Single hand action. There is no turn to the right of the hands therefor no turn roll to the left. It is the body turn that makes them appear to turn and roll.
IN EITHER CASE: the hands control the club- the forearms follow suit. I never gave much thought as to what by forearms were doing- just my hands.
Might not be the answer you were looking for but....
Burner- bad pun
** additional info. The Hands turned to the right need a roll back to the left and is part of roll/swivel/horizontal Hinge action/swivel that is used by Swingers. That is why this Standard Hand Action is perfect. Slicers hardly ever fully return the hands via the roll, let alone HH and swivel and finish the pivot.
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?
