Downstroke shoulder lag
In 7-13 Mr.Kelley talks about shoulder turn and downstroke shoulder lag. "Keep that right shoulder "back" but also "down" (on plane)"
Does this mean the right shoulder would have a dragging, passive feel through impact? Accomplished how? I had always thought of driving the right shoulder to the ball. BTW I'm a swinger.

Yes stilltrying,
Please take a look at 10-13-D and the accompanying pictures. This is what the right shoulder should be doing on the downstroke.
Anything other than " back" and " down" will mean that you are " roundhousing" per 2-N-0 and " run out of right arm" per 7-13 and have no follow through per 8-11 and 6-H-C.
What do we mean by " back" and " down"?
They have to do with Plane Angle and Attack Angle, because per 7-13, " When the Shoulder moves on the same Downstroke Plane as the Hands, it provides its greatest support and its best guidance to the stroke."
Please see 2-C-0 in this respect: " Your main lines of defense are the Flat Left Wrist, Hinge Action...and a Three Dimensional Downstroke - that is, DOWNward (Attack Angle), AND OUTward (Plane Angle) AND FORward (Approach Angle)..."
Referencing 10-13-D #3, which is a down the line perspective, the right shoulder stays " back" and did not roundhouse over the plane line.
From a face on perspective per the pictures from 8-7 to 8-11, the right shoulder works down and then below the left shoulder, not stay level with or go higher than the left shoulder.

Very nice Captain Silly Puddy!

Right Shoulder Lag, Drag and Thrust
Stilltrying,
Thank you for your support of our site over this past year. Your posts always inspire constructive thinking about the Golf Stroke, and we appreciate your contributions.
In the above Private Message to me, you asked for help in reconciling the Feel of Lag and Drag in the Downstroke Shoulder Turn with its role in supplying the initial Down Plane Thrust of the Power Package. In fact, the core concepts of Lag, Drag and Thrust constitute Step Two of the Power Package Sequence of Operation (6-0) -- Power Loading (6-B-0).
During the Start Down, the Thrust of the leading Body Turn and its Accelerating Right Shoulder transports the lagging Arms and Club Down Plane (6-K-0). This Action creates the Clubhead Lag Pressure that the Accumulators (via the Hands per 6-G-0 and 6-P-0) will propel toward Impact (7-22). This Load is sensed as a Drag on the Pressure Points employed. The Right Shoulder, having been placed On Plane by the Backstroke Pivot, remains On Plane by Turning directly toward the Ball.
The important thing is that, having Loaded the Lag, the Body Turn then continues to lead the Power Package throughout the Downstroke. This move -- On Plane Body Momentum Transfer -- transmits the Pivot Motion to the Arms (7-13) and thus constitutes both Aiming and Thrust.
However, a vicious Thrust is not required and, in fact, can be disruptive enough to cause Clubhead Throwaway (7-20). This is true even when applying Maximum #4 Accumulator Power, i.e., maximum Shoulder Turn Thrust against Pressure Point #4 (where the Left Arm contacts the side of the chest) during the Start Down (6-B-4-A). Every player has a top Turning Speed (2-M-3) and hence Handspeed (7-20), and no amount of violent effort will change it much. So, after supplying the initial Acceleration of the Power Package, the Body need only continue to lead in order to maintain its place in the Downstroke Release Sequence (6-M-1).
To grasp this concept, visualize yourself running toward a distant object. How long will it take you to reach top speed? Once you've reached this speed, can you do anything more -- pump your arms harder, twist your torso violently or even grunt louder -- to make yourself run any faster? No. And so it is with 'extra effort' and the Pivot Motion.
Regarding Feel, the lagging Arms, Hands and Club put a drag on the leading Right Shoulder, and this Feel should be sustained until the Release of the Power Package Accumulator Lag (Out-of-Line condition of the employed Power Package Components). However, just as with the Clubhead Lag (trailing Clubhead Inertia), the Pivot Lag (Lag and Drag of the Pivot Train) is never 'Released' (6-B-0). This gives the Stroke its Maximum Radius (from the Feet to the Sweetspot) and makes the Club very 'heavy' (Effective Clubhead Mass per 2-M-2-2) and much more able to resist the Deceleration Force of Impact.

Nice description Yoda.
In fact, the Swinger's massive rotor (Pivot) needs to slow down -- not acclerating or staying at constant speed -- for Momentum Transfer to take place from the Body to the Arms and Hands. This is how the Left Arm gets blasted off the left side of one's chest, so Centrifugal Force can be 'set up' to work its magic. If there was constant acceleration or even constant speed of the Pivot, the Swinger would never be letting Centrifugal Force take over the Rhythm of the Downstroke and there would not be a slowing, overtaking process happening joint by joint that is necessary for Momentum Transfer.
All this is quite counter-intuitive because we think how it is possible for something to slow down to speed something else up. Maybe this is the science behind one of the cliches we often here from our friends and golf magazines: "swing easy if you want to hit it further".

I agree Yoda, but can you clarify by what you mean if Pivot Lag were to be Released?

when?
"In fact, the Swinger's massive rotor (Pivot) needs to slow down"
At what point would this happen? Am I correct in assuming at this point CF would take over and then pull us around to finish?
Thanks.

If the Pivot Lag were to be Released, the Swing Radius would stop at the 'break.' For example, if the Shoulders were to overtake the Hips, then the Swing Radius would extend only from the Shoulders to the Sweetspot. And not from the Feet to the Sweetspot.

I agree that the "massive rotor" slows down in order for the " Momentum Transfer to take place from the Body to the Arms and Hands. But, beware not to do it intentionally, which might cause early release of the "lag".
The "lag" (from the pivot to the clubhead) should be intentionally sustained as long as possible to insure the existance of "thrust" through impact for resising the "impact deceleration".
The "lag" eventually will be "thrownaway" (sometime during the swing), no matter how hard/long it is intended to be sustained. But, make sure it is intended/allowed to happen beyond (way bepond), instesd of before, impact.

YOU load and sustain the "LAG", during which the " LAW" releases it, ideally beyond impact.
"Sustain ( Yang/陽) the lag ( Yin/陰)" is "the unification of Ying and Yang" ( 陰陽合一).
The " LAW" creates the " effect", which is the "motion" or "feel", with the " cause", which is the "intent" or "command".
" Lag" is the secret of golf, passion is the secret of life.
Think as a golfer, execute like a robot.
Rotate, twist, spin, turn.

Thank you Mr.Blake this last paragraph clarified a great deal for me.

Are you saying there is never an overtaking rate of the Pivot components...just always lagging?
