For me, the practice session has several objectives.
Practice errors that occurred in matches until they are no longer a weakness.
Practice use of the different spins for the same shot.
Practice different CB speeds for the same shot.
Practice different shooting positions.
Practice combos, caroms, banks.
Practice running as many balls as possible.
Practice breaking up clusters.
Practice bumping balls into other positions.
A proper practice plan is not the same as what is practiced in a practice session. A practice plan is a long term path where as a practice session contains what is needed to move along the practice plan path.
A proper practice plan requires an honest evaluation of your skill set, ie. what skills you are weak in. Then a path, practice session, is created to follow in order to eliminate those weaknesses. What is in the practice sessions will change over time as your skills set increases. What is in the practice sessions of a new player, will not be in the practice sessions of more advanced players. As ones skills grow, the required contents of the practice session change. Well, hopefully anyway.
A proper practice plan requires long term commitment. You can not practice once a month and expect to improve quickly. To truly master the games of pool is a life long goal, commitment.
But the real improvement will not occur until you start to ask yourself this one question...."Why do I still miss?"
This is not the same as....."Why do I miss?"
The first question only comes after hours and hours and hours of practice. So much practice time that you can not understand why you missed.
This is when the real practice starts. Cause the quality of the practice sessions depends solely own your mental skills and very little on your physical skills like when first learning pool.
It has become all in your head, and this is the hardest form of practice there is. Not getting rattled. That is very hard to practice. There is no system, no dvd, no book, no nothing that will help. Only by being in the heat of battle will help.
Which needs to be part of the practice plan. A way to measure how well you are practicing. This is what competition is for. To see how well you have been practicing and what needs further work.
Anyway, just one bangers way.......
