It's rather obvious you aren't actually looking for answers, since this topic has been discussed to death on here. And everyone of your claims have been shown to be just that, claims. With no basis in fact. Yet, here you are again saying the same old stuff. One has to wonder what you are doing here asking the same questions when you don't want answers to them.
For those that do want the answers, they are here- http://forums.azbilliards.com/showthread.php?t=331440
Well, while others understand the simple fact that when one side of a seesaw goes up the other side goes down...
& while very many, if not most all, understand that a computer with all of the scientific formulas programed into it can certainly be more accurate than a piece of wood with pencil on it, even though that was a rather good attempt,
you seem to be stuck in the stone age & would rather put your faith in the like over the science that you so often champion, at least when it suits your purpose.
May God Bless You, Neil.
PS I'm also sorry that you don't seem to understand what it is to ask a rhetorical question.
