When using a Hit Stroke, Angled Line Delivery Path of 10-23-B was the missing part in my machine. I found it in 10-14-B while taking out the slack without realizing it. The previous posts jarred my subconscious. What a flash of light as I read those words:
"the Hands take a nearly vertical path to the Elbow [Plane] Angle" before they begin their Straight Line drive "directly at and through the Aiming Point."
And MJ’s: “Right there in plain English, and I've somehow managed to not see it! Thanks.”
Glad my body knew what to do while waiting on the noggin to wake up.
