To those who are interested in my review papers, I have published a new review paper on the "power mechanics of swinging, hitting and swing-hitting". perfectgolfswingreview.net/powermechanics.htmError-correction suggestions and positive/negative feedback will be appreciated. Jeff.

Jeff, I am reviewing the paper right now and just will post questions as I go. They are not always specific to swing hitting but just things that cross my mind as I read. 1. Looking at the photo downswing sequence of SMK you state he releases PA Four...general question. If one releases PA Four correctly will there be some space between the left arm and arm pit as I can see in SMK photo #3 downswing sequence? 2. In my own personal swing the goal is to use a strong grip, a backswing that does not have a lot of LAFW rotation so that PA #3 is close to zero'd out, in this case would such a movement in theory reduce the amount of torque needed to square the club face, and in theory reduced the chances for mechanical error of adding torque force to get the club square? 3. Image 3 is close to the ideal that my current swing instruction is striving for, the club shaft should be very close to in line with the right arm and should drop below the plane as SMK recommends, the difference between AK's swing though has to do with her shoulder alignments at this same point, in my opinion she is to closed at this point, and maybe to much axis tilt because she is starting to get the club below plane. Four.(my labtop four button is toast) This is very interesting statement because it echo's what my teacher has told me about why we want a pitch elbow, I am not sure we are adding the same torque forces but with the other mechanics we are adding in with the shoulder motions (see this thread for a good discussion of what I mean www.lynnblakegolf.com/forum/thread7856.html) that a punch elbow would lead to OTT move.

Greg,
You asked-: "1. Looking at the photo downswing sequence of SMK you state he releases PA Four...general question. If one releases PA Four correctly will there be some space between the left arm and arm pit as I can see in SMK photo #3 downswing sequence?".
Not necessarily? It is possible to release PA#4 more downwards and therefore still keep the upper left arm against the left pectoral area. As long as the distance between the left hand and the right shoulder socket is increasing, then PA#4 is being released.
You asked-: "2. In my own personal swing the goal is to use a strong grip, a backswing that does not have a lot of LAFW rotation so that PA #3 is close to zero'd out, in this case would such a movement in theory reduce the amount of torque needed to square the club face, and in theory reduced the chances for mechanical error of adding torque force to get the club square?"
Being slightly slightly underplane would reduce the amount of torqe force needed to release PA#3 (according to SMK) - even if there is a lesser amount of PA#3 in play because one has less left forearm roll that is going to happen prior to impact (when using a strong left hand grip).
I don't know what you are referring to re: that LB-thread.
Jeff.

Jeff
In your second youstream broadcast i mentioned to you that i was struggling with a left arm/leadside swingers action, mainly that i was using pressure via my right thinger/thumb area to speed up the release but i was concerned that this was more of a hitting action than natural release in a swingers action.
Having read your latest review paper where do you stand on that particular issue now ?
Do you still believe that a player like mickleson doesnt use the trail arm hence the fingers coming off the grip slightly in the follow through or just that he applied the pressure with the trail arm for a split second then stopped before entering follow through ?
