You bring up nice points...

However.....Mac is not using the Straight Line delivery path and Zero Shift...With all due respect....He's not even using the Single Shift...

He uses a Top Arc/Angle Line for this particular shot requires a Double Shift back down to the Elbow Plane...

He started on the Hands Only Plane...I doubt this is his pre-selected downstroke plane...

You're right the Shoulder doesn't move down the Turned Shoulder....Why?

The right Shoulder is Turning on the Rotated Shoulder Turn which is at Right angles to his Spine...That being said.... the flatter planes such as the...Elbow and Hands OnlyPlanes... the Shoulder may move on a path that is "Parallel" to the Plane Angle rather than the recommended ON Plane Procedure which provides support to the Hands and the Club....

Checkout the stripes in his shirt in Frame #7...Not on-plane but....Parallel to the Elbow Plane?

This is another reason why Mac ..sets-up and has the amounts of #3 Accumulator, Waist Bend and Knee Bend....

You don't have to use the recommended pattern in Chapter 12 to be a real player...But I recommend you learn Chapter 12 before you customize it...

BTW...noticed he missed Qualifying School again....There's more to the game than a great swing and striking it pure.....Hmmmmm


Back to the pics....

The nuts and bolts are represented by frames #5,#6,#7


The significance ....is you can locate a Turned Shoulder Plane with a Rotated Shoulder Turn ...You don't need to be Standard and you don't HAVE to set-up on the Turned Shoulder unless you're lookin for a Zero Shift...I bet you asking why would he not use a zero shift...Well maybe his intentions are not to hit a straight ball? Perhaps he enjoys a stroke pattern that allows a little versatility? Rather than the "Uncompensated" recommendation in Chapter 12.
