If a straight in shot where shot from an edge to A 15* 'perception'...
then would not the manual 'pivot' have to be equal to a 15* differential...
in order to counter being on that line that is off by 15* to the true straight line shot?
If that is the case, as it would certainly seem to be a requirement, then what about ALL of the other shots?
Is one approaching ALL of them from 15* off of the true line & then the 'pivot' is then putting them back onto the true line.
If one is making the same defined pivot or sweep for ALL of the shots, then that would certainly seem to be the logical conclusion.
I did such a straight shot experiment yesterday, at the request of a CTE advocate. It only confirmed to me that there are variances needed from the described outline.
I could not make the precisely defined 1/2 tip 'pivot' negate the 15* angle & get back to the straight line shot. The ball cut left every time when done objectively & looking at the CB to be precise.
I could ONLY do it when I looked at the OB & varied the 'pivot' by adjusting the whole orientation of the cue stick to get it on line.
I think Dan White had similar results when he was shooting the infamous 5 shots 'perception' shots. When he looked at the CB & performed the 1/2 tip pivot purely objectively, he did NOT pocket the shots, but when he too looked at the OB & allowed himself to place the cue stick however appropriately as he saw fit, he did pocket the balls.
I know what that tells me, but I will leave it to each individual to make their own determinations.
Best Wishes to ALL During This Season.
PS I understand that 15 is just a round number for discussion purposes.
