Using Ghost Ball Contact Patch to understand aiming geometry

[JoeyInCali]

I saw a guy the other night lining up a severe cut back into a being pocket. He was standing behind the shot eyeing it up then he got right up close and fingered his chalk, then made a smudge on the table of where the ghost ball centre should be. It reminded me of this thread for what ever reason. He missed the shot horribly by the way. Maybe he didn't account for throw, maybe he can't accurately find the exact centre of a 2 1/16" imaginary cue ball, but it was maybe a 2 in 10 chance of making the shot... Pretty tough.

How ever you choose to learn to pocket balls just pay attention to every shot and how the balls react. Eventually if you want to have the luxury of playing on auto pilot you have to go through a few stages. Visualising the shot to aim the shot, instantly being able to pick out the line of aim... Then eventually being able to not think about pocketing balls... That's when the game becomes fun.

i liked this video. it gave me a much better idea of what the basic concepts were of the aiming systems discussions of late. it has been hard to sift through the noise to get to the signal.

I agree. I wish we had a dedicated moderator to weed out the people who only serve to disrupt and poison the technical discussions.

Say you got a OB close to a corner pocket, bout 3 inches. For a center pocket hit, the angle the CB comes off the OB is not right for the next shot. You need to hit to one side of center pocket to get the right angle for the cb to come off the OB.

Say it's the right side of center pocket. This means the ghost ball contact patch must move to the left along the aiming arc. How much is done by feel, but it is known the the margin of error is big being this close to the pocket.

Now move that shot setup 72 inches from the pocket. Now the margin of error is way smaller requiring a very precise hit on the OB, to go right of center pocket, due the the increase of distance. The direction of ghost ball contact patch is the same but the amount that it can be move and still hit right of center pocket is smaller than when closer.

Using the above example....explain using CTE. Explan how CTE allows for hitting anywhere in the pocket on purpose and not just in the pocket. What references does CTE provide in putting balls where you need them?

If it's a center pocket system only, then it can not. If it can put a ball anywhere in the pocket, it is impossible to do so with the same set of visuals as a center pocket hit.

It can not use the same visuals since the CB contact patch needs to be in two different locations along the aiming arc, one for center pocket, one for right of center pocket.

Um....you get the shot line for a center ball hit and then adjust slightly to favor the side of the pocket you want the ob to go to.
