This is in conjunction with another thread about getting lessons.
For those of us who have been playing many years change comes with greater difficulty. I do develop bad habits over time that have to be corrected and if the "fix" lowers my performance I drag my feet starting the practice for the correction. The correction then has to be integrated into my competitive game with either conscious effort or I can hope for the integration to occur naturally over time as practice makes comfort.
How much time does it take for you old dogs to affect substantive changes to your game and how do you do it. I realize by now we all play perfectly but I would like to hear every ones thoughts and/or experience on this.
I think there are a number of important factors to be aware of anytime you "tinker."
First off, there is the issue of whether or not a particular change is actually an improvement. Just this week, in practice, I made a minor adjustment to my PSR. In practice I thought that this "refinement" was an improvement. The next day I had a money match and played poorly the entire time. So the next practice session I'm playing with the two versions and realize that, for a number of reasons, the original is actually the better version. (It also reconfirmed my long standing belief that, in practice, you can convince yourself of almost anything -- but under the heat you learn what really works.)
Which leads me to a second issue: rarely, if ever, does a change to your mechanics not change something else in your PSR. And that makes it tough to isolate what is actually causing an improvement, or degradation, to your game. Change a grip and it probably changes your alignment. Change a stance and it probably modifies your footwork. Change a bridge and could alter your set up sequence. And all of those down stream alterations are often difficult to detect and evaluate.
A third issue is that it is often difficult to clearly identify the exact parameters of a change to produce consistent results. IOW, it is very easy to misinterpret the exact nature of a change. One day you may decide that a shorter (or longer) grip makes your stroke more accurate, powerful, gives you better touch, whatever, when it could easily be that the grip change was altering something else like the elevation or alignment of your cue, or setting you up further or closer to the cue ball, or even just causing you to move more slowly or faster, and one of them things was actually the root cause of the change in your performance.
Lastly, because we are not robots, changes tend to migrate. We start out paying careful attention to a change and then, over time, or in the heat of battle, we pay far less attention to it and the change erodes into something else and we wonder why our "fix" is fixing any more.
So, change is tough. You have to nail down a number of issues that are not so obvious. But then, no one said this was an easy game.
