[O.B.Left]

Just reading all this. John, re Homers drawings of 2-C.

- they are not to scale. Not even close. The ball is about the size of a tennis ball for instance, vis a vis the club. I assume Homer did this to make the underlying geometry more obvious to the reader. To make the drawings more illustrative.

-the "ideal application" or 2-C-1 represents the ideal of total compression and therefor, per 2-C-0, assumes the point of contact between ball and face stay together, intact "as if welded together" throughout the impact interval. So if impact is prior to low point this mandates that the point of contact will go down plane all the way to it low point position (assuming the clubhead completes its orbit).

-separation is assumed to be at low point, so the shaft will therefor be vertical given a flat left wrist. You could also therefore deduce that Homer assumed a flat left wrist.

-if impact is made prior to low point there will be some shaft lean.

-shots that see the ball roll on the face even if it is solely a result of loft are not examples of "total compression". We golfers know this intuitively.....we dont tee up a driver on a 120 yard par 3 for instance. We choose a more lofted club for its inherent loss of compression. Why did Homer draw a somewhat lofted club in 2-C-1 2A then? I assume for illustrative purposes again. To highlight some of the vectors directions.


See 2-C-0 its an interesting read and concludes with:

"The Ball leaves the Clubface with a force proportional to the compression produced by Impact. Then the ideal result of the above procedures is maximum compression. But any clubface imprecision during Impact will permit compression to leak away. Lost compression cannot be re-covered. Between the precision Impact of 2-C-1#3 and the total loss of compression in 2-C-3#3 , there can be every degree of Compression Leakage--some intentional (Back Spin) but mostly unintentional. 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) per 2-C1#2 A/B. Study 2-H, 2-N and 7-3. "

He then goes on to list Newtons first three laws.

You'll notice a relationship between the drawings of 2-C and Steering. Intentional compression loss vs. unintentional compression loss due to a common conceptual problem.

Can you see these things in slow mo? Id say yes, you can see Steering....guys verticaling a driver say... But impact is violent and distorts all of the parties to it: ball, clubface , clubshaft and clubhead. So you have to look before and after impact to see what going on.
