Dariusz,
I am delighted that you have expressed your opinions re: hand release actions, because it gives all forum members and guests an opportunity to perceive your personal perspective on the issue. Having forum members read and analyse different personal opinions is intellectually enlightening and reflective of the value of an open golf forum.
I am always willing to consider alternative opinions because it gives the me opportunity to reconsider, and revise, my own personal opinions re: golf swing mechanics/biomechanics. However, in this particular case, I have no reason to change my personal opinions because I think that your opinions are totally wrong-headed.
The underlying philosophy of your personal opinion re: hand release actions is that the type of hand release action used by a golfer is not a deliberate/conscious choice, but rather than the end-product of underlying biomechanical factors relating to the pivot motion and the degree of secondary axis tilt. You believe that certain combinations of pivot motion and axis tilt create conditions that favor a certain type of hand release action. In other words, you believe that the likelihood of a golfer using a certain hand release action happens subconsciously and without deliberate/intentional control - as a subconscious reaction to biomechnical events happening with respect to the pivot motion and the degree of spinal axis tilt.
I cannot think of golf swing mechanics in that manner, because I believe that optimum golf swing biomechanics/mechanics depends on deliberate/intentional choices that a golfer makes when developing a golf swing action. I believe that a golfer must rationally decide which type of hand release action he should use - based on the reliability/consistency of that hand release action in efficiently controlling the clubhead path and clubface angle through the impact zone (roughly from P6.5- P7.5). I believe that the only rational choice is to use a DH-release action - either a no-roll hand release action or a full-roll hand release action. To optimally perform those two types of DH-hand release action in an efficiently consistent manner, I believe that a golfer must maintain an intact LAFW/FLW through the impact zone (between P6.5 and P7.5). However, I also believe that the best way to ensure that one has an intact LAFW/FLW throughout the impact zone means that a golfer should have an intact LAFW/FLW throughout the swing action - specifically from P2 to P4, and from P4 to P7.5. In other words, learning how to have an intact LAFW/FLW throughout the entire swing action is the keystone of an efficient DH-hand release action.
Secondly, I believe that after a golfer has learned how to maintain an intact LAFW/FLW throughout the swing action, he also needs to understand that the optimum delivery of an intact LAFW/FLW through the impact zone (roughly between P6.5-P7.5) depends on optimizing the pivot motion and arm motion so that they are perfectly synchronised. If a golfer lacks the flexibility to perform an optimal pivot motion, then he must alter his arm motion so that they still remain perfectly synchronised. However, that doesn't mean that he should believe that he must give up on the idea of playing golf with an intact LAFW/FLW or give up on the idea of being a DHer. I believe that a DH-hand release action is the only acceptable hand release action and it can either be a no-roll type of DH-release action or a full-roll type of DH-release action. I think that it is unacceptable to allow any forearm roll-over motion through impact (where the left forearm supinates and right forearm pronates between P7 and P7.5) or any horizontal left wrist motion at any time point between P2 and P7.5.
Some specific criticism - you wrote-: "c. the secondary axis tilt (upper body angle) -- now listen carefully; the greater it is the easier is to maintain wrist angles longer after the true low point on the ground since (excuse me not professional explanation) the shoulder girdle is being tilted creating a virtual low point farther targetwise and up -- which is very logical taking into account the wrists start to bent at the low point of the arc naturally (due to both physical forces applied as well as anatomical possibility of RoM in this area)."
I disagree that increasing secondary axis tilt moves low point targetwise. I think that it moves low point away from the target - because low point is under the left shoulder when the left arm and clubshaft are in a straight line alignment and vertically-oriented. If a golfer has increased secondary axis tilt at impact, that means that the left shoulder socket must have moved away from the target. I also think that low point of the clubhead arc is only determined by the straight left arm/left shoulder girdle and the right arm/right shoulder girdle play no role in determining the position of low point of the clubhead arc. I also don't believe that the left wrist should naturally bend at low point - if a golfer chooses to maintain an intact LAFW/FLW throughout his entire swing action from P2 to P7.5 and I also believe that there should be no alteration in the shape/direction of the clubhead arc secondary to allowing any left wrist horizontal motion to happen at any time point between P2 and P7.5.
