You ARE wrong about the vast majority of shots. There are actually very few shots that baseline geometry in conjunction with a properly executed stroke and properly executed BHE doesn't work. I was one person who was able to duplicate your system if you're doing what I did, which I'm not entirely sure of, but accurate geometry is perfectly accurate in the vast majority of cases.
Hi,
Thanks for your comments which are always informative...and courteous. I appreciate that.
But likely due to flaws in explaining myself, your comment above actually confirms my position...which is....On shots other than those that are relatively close to the intended pocket, a cue ball rolling forward WITHOUT ROTATING ABOUT ITS VERTICAL AXIS (spinning) when contacting an OB on its line of centers toward the pocket (its geometric path) will NOT cause the OB to travel that path due to the operation of collision-induced throw and therefore, those who argue that the
geometric LOC path will be traveled are simply wrong (assuming the balls collide at MOST (but not all) angles to the LOC path.
The operative concept central to my thesis is that the CB is NOT spinning.
Of course, if it IS spinning THEN the path of the OB CAN be made to travel the geometrically derived path but the shooter must apply some sort of force causing the CB to spin for that path to be made good.
I have used the phrase "raw geometry" to qualify my statements and "raw GEOMETRY" cannot be convoluted to suggest the imposition of a force in PHYSICS.
So, in your example, you refer to the use of BHE which, of course imposes spin and therefore removes the shot from the realm of raw geometry.
Therefore, I think that we actually agree.
I have given BHE the old college try and it doesn't work well...for me. Possibly due to the "old dog, new tricks" issue but I would like to think that the reasons are the fact that I use a low deflection shaft (predator) and that my bridge distance doesn't accommodate the use of BHE...both of which are the factors that Bob Jewett cites in a 2004 article as reasons why BHE might not be right for everyone.

So, for the avoidance of doubt, my position is that...To a degree that increases with the distance from OB to pocket, cut angle and less-than-perfect ball condition, an OB will not trace the path suggested by raw geometry UNLESS the shooter imparts spin to the exact extent necessary to counteract collision induced throw.
Therefore, given the not precisely predictable magnitude of CIT and the equally imprecise nature of imparting spin, the EXACT amount of required spin would be imposed largely by chance and therefore, directing the CB exactly along the LOC path would also occur largely by chance..although, nevertheless, the OB may drop due to the margin of error permitted by the pocket.
But the suggestions..."Raw geometrric aiming works EXACTLY" and "Shots aimed with raw geometry will go if the OB is close enough to the pocket that it will drop in spite of the erroneous raw geometric aim" are WORLDS apart.
WHEW!!!
Bottom line...I think we agree about the geometric path not being traveled assuming a LOC contact point hit without the imposition of spin.
Right??
FINALLY, what makes this whole line of discussion non-trivial as that even the most learned authors (and those who post diagrams on forums) routinely depict shots based on raw geometry.
EVEN Byrne does so in "Standard Book" at page 24 (1987 edition,Chapter 2 Center Ball Shots) when he begins to describe how to line up shots. His graph and text suggests the LOC CP method of lining up a 20 something degree shot.
I HASTEN TO ADD THAT HE HASTENS TO EXPLAIN (beyond page 24) all that needs to be known about CIT and why aim must be adjusted to compensate...BUT someone could post THAT PARTICULAR diagram and swear that it stands for the proposition that Byrne knows nothing about CIT and thinks that the geometric path will be made good.
There are posts in the threads that ADAMANTLY testify that the "raw geo" path WILL AND HAS TO BE made good...but of course, on a center ball hit...it WILL NOT AND CANNOT BE made good...even with brand new balls.
Are we on the same page? If not, I will be genuinely interested in your counterpoint.
Regards,
Jim
