When I use the term upcocking, I am only referring to the process of radial deviation of the wrist. It has nothing to do with the "backswing" per se. I should just stick to HK's use of the term "cocking" and stop using the generic term "upcocking".
I cannot really understand the "issue" that Golfbulldog is exploring. He seems to be exploring the relationship of the left wrist cock action relative to a single linear plane (like a glass pane which is only generally representative of the clubshaft plane in the downswing). I believe that the left wrist cock action can only be perfectly in plane with that glass pane (in a linear sense) at a single moment in time - when the curved path of the left wrist cocking action (left arm flying wedge action) is exactly on that glass pane and parallel to that glass pane "somewhere" in mid-downswing. That "somewhere" point primarily depends on the rate of rotation of the left arm flying wedge during the downswing relative to the degree of dropping of the hands down to the ground in each individual golfer.
The point that I was making about the curved left wrist cocking plane and its relationship to the clubshaft only has relevance to the intrinsic relationships within the left arm flying wedge unit - when the clubshaft is at right angles to the left arm unit, and the left wrist is always flat, then the clubshaft must always travel in the same curved plane as the left arm. This "curved-on plane" inter-relationship between the left arm and clubshaft must change dramatically during a swivel action when forearm action causes the flat left wrist/hand unit to supinate (close) relative to the overall left arm/hand movement arc.
Here is an example.
This series of images represents the release swivel action. The clubshaft is swinging down the inclined plane, but the left wrist uncocking planar action is totally unrelated to that inclined plane - because the entire flat left wrist-hand unit is swiveling counterclockwise during this time period.
The general point that I am attempting to make is that relating the i) plane of left wrist uncocking action to ii) a single inclined clubshaft plane (generally represented by a glass pane placed on the ball-target line baseline and inclined at a certain angle) is meaningless, because it depends on iii) the degree of rotation of the left arm and iv) the degree of dropping of the hands per unit time during the downswing, which is individual-golfer dependent.

Homer Kelley referenced the wrist conditions in chapter 4 and is basically describing three 90 degree circles of rotation around the left wrist center. In 3D terminology these are labeled the x,y and z axis. Homer Kelley on the other hand labeled these horizontal(bent/arched), perpendicular (cocked/uncocked), and rotational (turned/rolled) and appear precisely in the same order as x,y and z. Homer Kelley's intentions could not be any more clear on this.
As an analogy, think of a globe and imagine the equator and 2 circles drawn from the north and south pole whereby all intersections of these circles are at 90 degrees from each other.
Both the horizontal and perpendicular circles of rotation will influence the club on a flat plane. These circles will also influence the movement of each other but not the rotational or z axis is the fixed constant around the rotation of the left wrist.
To think of the 'perpendicular' (cocking and uncocking) displacement as taking place on a curved plane is incorrect unless your 'reinventing' what has been one of the most basic cornerstones of engineering and mathematical knowledge as has been practiced for the last few centuries.
The displacing effect with the z-axis is somewhat more tricky to explain but not so difficult to understand once you can visualise it. When the club is directly opposed to the rotational plane it has no displacing effect other than turning it in a conical shape around the longitudinal center of gravity. When it is on the rotational plane, then it will move on a flat plane. When the club is between these alignments the club will now get displaced in a conical movement. However, the displacement of the club is still always still taking place with regards to its 2D axis.
Mechanically without anatomical restraint any two of these axis can move the club anywhere around the left wrist center whereby Homer Kelley outlined the possible wrist conditions in the standard flail of 2-K...
Now I cannot be bothered typing what I said before so let me just copy and paste here.
-----
If the left wristcock takes place without a bent or arched condition, it moves on a plane that is aligned with the left arm. Since the left arm is not onplane and it is above plane therefore the left wristcock plane CANNOT EVER be aligned to the inclined plane.
------
However if you wish to use the sequenced release you must align the perpendicular axis to the inclined plane inorder to make it independant of the rotational axis, the horizontal axis must be employed.
However simultaneous release is possible without any movement on the horizontal axis. Homer Kelley may have known this as he referenced that he believed that both swingers and hitters should use hitting alignments, and that his entire premise of clubface control was based around using two axis or rotation. I could make many arguements against this premise however mechanical advantage, and what constitutes swinging is not at the heart of this thread.
As a critique of Homer Kelley, this produces many contradictions in the book where some parts are actually misleading. On the other hand, I can understand Homer Kelleys intentions for simplicity inorder to get through to those with occult idealogies as the hitting alignments Homer Kelley suggests is indeed simplier than the swinging pattern I would suggest to intellectually grasp and explain. It is a system but a system based on an adaptable 'hitting' pattern and in that respect the book is perfect. However preforming a sequenced release with a 'flat' left wrist is hogwash that needs to be throughly disposed of.
