Here're a few thoughts on practice... (Long post!!)
First of all, and most importantly, I make a plan before I go. I cannot stress the utility of this enough. Decide what you're going to practice and for how long before you leave the house.
My practice sessions are usually in the region of 2-2.5 hours (I usually pay for six games, which take me about 2 hours or so). I try to be fairly regimented about my practice to make sure that I get as much out of it as I can.
The other thing I find most useful is recording. Make a note of what you're trying to accomplish during the practice and see if you accomplished it (obviously, the way you do this will depend on what it is you're trying to look at)
In my pre-practice planning session, I will try and think about whether there's anything that I have specific concerns about in my game, normally I try and jot these down so I don't forget them later.
I have been coached by Dick Ritger among others, and find great utility in using and applying the drills that I have learned.
So, I warm up with 4-5 shots first, this is usually enough for me to loosen the muscles and get warm and start to feel for the ball coming off my hand nicely. Then I move onto the foul-line drill and will spend about 0.5-0.75 games on that, noting things like balance and release-feel. I also use this time to add pieces of tape to my thumb where necessary to achieve a proper fit. Then I'll move onto a two-step drill and spend about the same amount of time on that, again thinking about balance, release, and relaxation in the armswing.
Then I'll pick a medium ball and make a few shots with it using my full approach, no more than 4 or 5 just so I feel comfortable with everything, and can find the approximate ball path to the pocket.
I then pick up my polyester ball and go through a full rack of pins one at a time, recording misses/hits as I go. I will attempt all ten single pin leaves at least 3 times in the two hours, but it can be as many as 6 depending on how my sparing has been of late.
Then over the course of a few weeks I'll look at accuracy over a range of targets, with a range of balls, recording my accuracy at the arrows and breakpoint (sometimes using tape at the breakpoint as a marker).
If I have any specific concerns like balance or timing then I've got specific thoughts I can trigger which make me think about the causes of my issues there.
And that's pretty much that
