I want to do a video on this because its a difficult to grasp part of my findings but I think I need a textual answer to this also.
When I said that all strokes roll to the plane, thats not entirely true.... I just said it to basically not enter into a whole maze of debate which I will unleash on you now..... Im not opening two cans of worms at once... Another reason I stated it was because I wanted to bring to your attention the dynamic nature of wrist conditions....
I wanna talk about the roll of the hands through impact.
With the onplane flail of 2K there seems to be some problems with transitioning into a vertical flail as described in 2K as you go into followthrough because of the release point on the downstroke and how the wrist conditions dynamically adapt with the rolling of the left hand in accordance to the precise location to the orbit around the left wrist. You see the problem is if you use the vertical flail phylosophy is that it disrupts the rate the clubhead orbits around the left hand because in a vertical flail model the wristroll has to work simultaneously with any wristcock motion. You can't have the rate of the clubhead around your left wrist is going at one rate and then another....
Thats when it hit me when I asked what if I took a conception from 1-L too literally. Lets say the accumulator 3 plane left club and hand where only mean't to be inline at impact then from this inline condition (see standard flail 2-K) preform a hinge action. So you would have a designated place for your hand into come into impact to a point that would mirror the vertical flail at impact vertical to the ground for all strokes but then doing different things from that point.... You see that would change everything - if the inline condition wasn't at the lowest point of the orbit (in relation to its center and not the lowest point to the ground plane - Mike O) directly under the left shoulder where all hinge actions would go to the same point like in the 1-L model.
Where the flail comes inline to that point of impact you then on the second half part of this orbit you can produce a hinge motion using the last remaining two wrist conditions wristcock and wristbend with the left wrist and hand to keep the club onplane. The left wrist and hand are still going to be vertical to their associted plane however however the rate of the clubhead around the left wrist has not changed. This is going to give different types of 'followthroughs' in the PGA manner of the word just like Tiger when he's trying to shape particular shots. Providing you use two axis of rotation around a point you can a use lever like a golf club inside any location within a spherical shape and thus using these two motions keep the club onplane whilst the third is 'locked' its relationship to the associated plane of the hinge action.
So after impact wristbend ?????? - wow this is fun and contraversial....lol
Your alternative is you can also keep your swivel motion rate either side to the flail mirroring the vertical flail at impact point but this will produce only a singular hinge motion.... a closing motion of the clubface thats speed is entirely determined by release point of the number 3 accumulator so you better have alot of trust to physics to produce the same result over and over which I believe and correct me if I am wrong - is what Ben Doyle tries to do in his model by means of regulating the roll by always going to maximum trigger delay.... however the left arm on the otherside when it bends after followthrough (GM definition) will oppose the inclined plane exactly the same when preforming a hinge action like I said in the videos.
Correct me if I am wrong - didn't Homer say a slightly arched wrist was good protection against a bent left wrist at impact?
I said inline at impact remember.... im talking about the dynamic wrist motions occuring after impact.... in relation to the rate that the clubhead is going around the left hand onplane.... whilst the ball is carried on the clubface....
I did maintain a 90 degree angle between the left forearm and clubshaft when I lowered my left arm to a 45 degree angle. However, I deliberately kept the clubface unchanged relative to the ground (and not relative to the left forearm) in the first sequence by keeping my left wrist very relaxed, while in the second sequence I kept the clubface neutral relative to the left forearm. However, to keep the clubface neutral relative to the left forearm in the second sequence, I actually had to actively palmar flex the left wrist while lowering the left arm.
The purpose of this little exercise is to suggest the possibility that one has to actively palmar flex the left wrist slightly to allow the left wrist to remain flat when the left arm is angled below left shoulder level in the downswing and the clubshaft is on plane.

But we are not interested in "relative to the ground"-only the selected plane?
I have a question about Sean O' Hair's hinge action. Just before the followthrough is complete (arms both fully extended) his left wrist swivels around to the left in an abrupt horizontal hinging-type action. This hinging action doesn't seem to occur as a result of a hinge action at shoulder socket level or body torso turning level. Is this abrupt left wrist rolling action normal and/or desirable?
Secondly, I note that he doesn't fold his left elbow after the followthrough, and I thought that a standard finish swivel action requires more folding/bending of the left elbow. Is that assumption incorrect?
