I talk to myself all the time when i practice and play racks about having good mechanics.

Can I give you a newbies perspective here, from someone in your position, Mike. As opposed to coming from the instructors. Someone said it earlier in the thread, you're thinking too much!
I'm saying this because it happens to me, too. Once I recognized it, and corrected it, I began making more shots, more often. I have to guard against it still, but now that I recognize it, I can work with it.
You're likely gonna say "but how am I supposed to focus on the mechanical things that I need to make repeatable?" I know this because I said the same things to myself, as well. To me, a novice at all this, it means working out all those things BEFORE getting down to shoot. Once there, just shoot the damned thing, and don't think about it! If you're literally talking to yourself about stuff while shooting, you have to be focused in too many directions, and concious of things that you might not be otherwise. When I tell myself "don't grip too tight", what do you think I do? Squeeze too hard, and that doesn't help, right?
Mike, you put a lot of thought into this stuff. Don't fall into "paralysis by analysis", or overthinking it. I know I have done so, all in the pursuit of "getting better". Once I started letting go of the thought process the moment I got down at the table, I stopped having as many problems as I did previously. I still have a LONG way to go. But the process is easier now, and FAR more enjoyable.
Is it Randy G that says "don't shoot in the thinking position and don't think in the shooting position"? It is so very true. Even to a newbie like me. Perhaps especially to a newbie like me.
Try to have some fun, Mike. It's supposed to be fun.
