Thanks Ted,Sorry to bother again,this would mean that my R/elbow is the tracing point,this would be shining at C/head path,yes
Homer said the light was from the Right Forearm through the #3 PP, not the Right Elbow. I was just making the point that a different Elbow Position, given your original assumption, would have the light missing the Delivery Line. It's tough to explain, but easy to demonstrate.
