Forget pivot point. Mosconi never knew what that was, I don't and ask Efren what deflection is. Listen to Hang the 9. And buy Mark Wilson's book and Get a lesson.
This is what helped my stroke. First, I read Mark's book (this was after a couple lessons with Scott Lee and Jerry Brieseth), but Mark's book really gives you a study-able template.
I set up a long straight in shot from corner to corner. (cue ball about 12 inches from the bottom corner and the OB about a diamonds length passed the middle of the table). I put the reenforcement donuts to mark the spots. I did this 100s
This shot provides invaluable information to correct what is wrong. It allows you to focus on a single variable at a time with instant feedback. DO NOT underestimate the stance and how you are lining up the shot. You MUST stay down on the shot afterwords to see where the stick ended up. And You Must not move your head.
Mark suggests that after EVERY shot you ask yourself how could I have stroked that better (good for mental game in competition as well).
Great advice PWH on fundamentals, but remember that you are competing today with people that DO KNOW WHAT A PIVOT POINT IS. more information is available more readily to people today via the internet. I don't think it's good advice to tell someone to dismiss basic easy things that can have a dramatic improvement on their game just because you yourself don't understand it. Stroke takes many hours of practice...pivot point basics can be taught in 20 minutes by someone who understands it. It comes down to ...play with a short bridge or a longer bridge depending on your shaft type. Easy.
Remember too that the age old school of training on bridge length was like a hand length away from the cue ball. Yes, in mosconis time. Ps, that's about...6" !!! That's because there were only solid maple shafts back then. Go figure...they were playing with bridge lengths that were matched to their pivot points!
Many players already have adjusted their bridge length to match their pivot point without even knowing it. They just know that they are most comfortable playing at that distance.
I ran into a pro some time ago that played at about 14"...and I asked him why he played with such a long bridge...he said...I don't know. Just feels comfortable to me. No surprise he was playing with a Z shaft. He had made those corrections automatically without knowing anything about pivot point.
I'm not saying that it's the fix all, end all, you still need good mechanics on everything else, but it can't hurt to match your pivot point in most cases.
Also, I'm not suggesting that bridging 14" is a great idea, cuz the Z has a ridiculous pivot point, but why not take a little time to see if moving the bridg 2" up or down still feels comfortable, and more closely matches your pivot point?
For example, if this OP has a maple shaft with a 6" pivot point and is playing at 10"......there's room for immediate improvement...on stroke accuracy and pivot point.
Where I think that new comers can get a little in trouble is when they start with a predator shaft with. 10/12" pivot point, and they should be using a 6" or less bridge length to stabilize their wobbly stroke. Seems like a predator would be potentially counter productive on shots where their stroke was off, and now it gets amplified by a gross difference in the pivot point.
