A predisposition of an action or intention before Impact which will cause the Left Wrist to bend or not to bend past separation notwithstanding, I am saying this - if the physics of the stroke are identical to the point past separation at which the bend will or will not take place, the ball flight will be identical. The ball doesn't know of this predisposition, it only knows what the clubhead does to it in the Impact Interval. And it is not affected in any way, whether the Left Wrist bends past separation or not.

Let's take Couples for example. At the both arms straight position past separation, his Left Wrist is well bent. Now he could preprogram himself to swivel prior to that, but still past separation, so that the bend did not happen, but the ball flight would be the same - the ball wouldn''t "know" thet the swivel happened.
