I put the OB between the long rails (2 diamonds) and 6 diamonds away from the head rail or 2 diamonds up from me. I place the CB 1 diamond close to me offset by 1/2 ball off of the center line between the long rails (right or left).
If I moved the CB 1/2 diameter to the right, the center of the CB is looking up table at the right edge of the OB and the left edge of the CB is looking at the center of the OB.
I shoot the shot hitting the CB dead center at the right edge of the OB or CTE and the OB goes into the left corner pocket. I trig this out to be 18.4 degrees. Geometrically, the cut angle should be 30 degrees so the shot was affected by cut induced throw CIT.
This 18.4 degree cut angle may be different for others who try because of other factors like cloth speed, humidity or...
For these reasons, it is futile to tie aiming to geometrically correct angles using a center ball hit on the CB - where many pivot and non-pivot aiming systems start at before the tip contacts the CB.
This could be a blessing to those that don't tie geometry to the actual cut angles achieved and only commit to memory the resulting cut angles for aiming at the edge other fractions on the OB or distances/points off of the edge of the OB.
This is also true for those that use the contact point on the OB that sends it to the pocket/target as a reference for aiming if the CB is hit at its center - english (off center) gets you closer.
Is this just me?
Be well
