I like this line of thought . . . So let's take this a little bit further. We are considering a Horizontal Plane for a second . . . We can still have the extended line of the Right Forearm Angle of Approach on a Horizontal Plane no? So let's just consider it as a line for now across the face of the plane extending in both directions (up plane and downplane). If we extend this line it is a DIAGONAL LINE right? So would it not stand to reason that much like the shaft traces the plane line, the end of your right forearm closest to the Plane Line would be ON the Right Forearm Angle of Approach maybe? So the the end of the Right Forearm would either be the Right Elbow or the #3 and #1 Pressure Points? So could it be that your EFFORT or DIRECTION is to take the elbow or the pressure points up and down the extension of that line?
Holla back.
If i understand you correctly Bucket ,it would be the #3pp you would trace the plane line with because the forearm doesn't stay on plane.The visual path would still just be a circle on a horizontal plane.
"The right forearm must leave ,and precisely return to ,its own fix position "ANGLE OF APPROACH" ".(I KNOW YOU KNOW THIS BUCKET-NO OFFENSE!!!)
