What do you think about Chris Ryan theorising that the bowing of the lead wrist subconsciously affects a golfers pivot action ?
I am assuming he is in agreement that a bowed lead wrist will cause the clubface to open relative to the ball-target line . But to theorise that the golfer will subconsciously be aware that the clubface is open and therefore prevents the golfer from stalling his pivot seems rather speculative to me.

Dr Mann What do you think about Chris Ryan theorising that the bowing of the lead wrist subconsciously affects a golfers pivot action ? I am assuming he is in agreement that a bowed lead wrist will cause the clubface to open relative to the ball-target line . But to theorise that the golfer will subconsciously be aware that the clubface is open and therefore prevents the golfer from stalling his pivot seems rather speculative to me. DG CR's opinion that having a bowed lead wrist at P6 has a subconscious effect on a golfer's mind and makes him use a more active pelvic rotation between P6 => P7+ makes no sense to me. CR opines that a golfer who has a bowed lead wrist at P6 will sense that the clubface is more closed than usual, which is only based on golfers who use a weak-or-neutral lead hand grip and the clubface will be only 20-30 degrees more closed than normal due to the execution of the reverse motorcycle move happening between P4 => P6. However, we know that the golfer will actually need more lead forearm supination between P6 => P7 if he maintains a bowed lead wrist all the way into impact because a bowed lead wrist at P7 (when the lead wrist is ulnar-deviated) causes a lot of forward shaft lean, which has a clubface-opening effect- and the golfer will need to enact more lead forearm supination during his PA#3 release action in order to get a square clubface by impact. That is clearly seen in Collin Morikawa's full golf swing action. Image 2 is at P6 and CM has a bowed lead wrist.
Image 4 is at impact, when CM still has a very bowed lead wrist, which causes a large degree of forward shaft lean at impact. Note that CM has to use more lead forearm supination to get a square clubface at impact - note that his lead lower forearm's radial bone is rotated more counterclockwise at P7 (image 4) than it was at address (image 1). When it comes to pro golfers who use a very strong lead hand grip, they basically never bow their lead wrist between P4 => P6. Here are capture images of Jamie Sadlowski at P6. Note that his lead wrist is extended.
Between P6 => P7 his lead wrist becomes slightly less extended because he angles his lead arm more outwards away from his body and he consequently comes into impact with a smaller accumulator #3 angle. The green graph represents his lead wrist flexion-extension graph. Note that his lead wrist is extended by >60 degrees at P4 and it remains extended during his early-mid downswing between P4 => P7. At impact it is still extended, but only to a small degree because he progressively acquires a smaller accumulator #3 angle between P6 => P7. The fact that his lead wrist is very extended at P6 does not affect the fact that he chooses to use a very active pelvic-opening pivot motion between P6 => P7. According to CR, having a very extended lead wrist at P6 would mean that a golfer would not use an active pivot rotary motion between P6 => P7 - as he demonstrates between the 1:43 => 1:46 minute time point of his video. However, that is because he is using a weak/neutral lead hand grip and having a very extended lead wrist at P6 under those conditions causes the clubface to be very open, and he therefore has to use a lead wrist flipping motion to get the clubface square by impact because he maintains a very cupped lead wrist all the way into impact.

Many thanks Dr Mann.
