Hey there Crackle,Don't have a clue, I don't play pool. All I can do is refer you to the above post that you referenced. Check paragraph three.
I don't know or care if you use parallel, pivot, backhand, front hand, or maybe even backwards english.
My point is very clear, if the tip contacts the CB off center to either side then it's some part of the edge of the tip that makes contact with the CB not the center.
You must have missed the two times I've posted on the other thread "I AGREE THE WORD SHOULD BE EDGE, NOT CENTER."
You should immediately open a class action lawsuit for wasting thousands of people's time, reading my inexact articles. For mistaking one word, I shall commit seppuku immediately.
