9. The magic of the right forearm: Cocking the left wrist without
cocking the right by bending the right elbow.

10. 1/16 of an inch of bend adds one ounce of effective mass.

Just to clarify...

The right Elbow "bending" in Item #9 does not relate to the word "bend" in Item #10. In the latter, Homer is referring to the bend in the Clubshaft, i.e., the Clubshaft stressed by Clubhead Lag Pressure Point Pressure, not the bend in the Right Elbow.

In his experiments, he was delighted to find that one inch of Shaft Bend added one pound (16 ounces) to Effective Clubhead Mass. Hence, 1/16th inch of bend produced an additional one ounce of Mass. Said he:

"Very nice that it worked out that way!"

This is the value the "pre-stress" (2-M-1 and 6-C-2-C) introduced at Start Down, usually by the leading Pivoti.
