The angle of the left arm as it enters the plane is always dictated by the length of the left arm going from the point of the left shoulder above plane to the hand into the plane... There will be a mathematical correlation (although this list may not be accurate or complete - just noting my thoughts) between the leftwrist cock, the angle of the left flying wedge into the plane, the swivel, the angle of the inclined plane and the starting point of zero acc#3 dictated by reference to the hinge action plane with travel relative to the inclined plane angle.

Heres another way of looking at it also - lets say you where entirely preforming a stroke with the left hand always staying vertical to lets say, the horizontal hinge action. Now if the wristcock was performed without a swivel also in this vertical plane then the clubhead is going off plane.... its going up and down vertical to the ground whilst the plane is inclined..... how can you get it onplane - the only ways is co-ordinately using the swivel in unison with the wristcock to bring it onplane - creating a simultaneous loading and release....

The circles that are created via #2 and #3 are at 90 degrees,and both need to be used relative to each other which will result with a simultaneous release and loading..... so what about sequence releases ...

Inside a sphere there are actually THREE 90 degree circles and at least two of them are only needed to move the secondary lever assembly anywhere inside a sphere but unless the motion is exactly on a single circle - at least two of them have to be implimented (with three combinations 1+2,1+3,2+3). Imagine a Globe - you have the equator (circle no.1) - Now draw a '+' side on top of the north pole and continue these lines all the way round to an equivalent '+' on the south pole (circle no.2 and no.3).... These three circles of motion that create a spherical motion of the secondary lever assembly are the left wristcock, the left wrist bending and the rotation of the forearm... since two have to be employed at any one time - for the wristcock to go from cocked to level with the clubhead onplane you must impliment a left wrist bend (double wristcock) to the negative degree of the left arm angle into the plane to inorder to align the circle of the wristcock motion to enable a sequenced release....
