obclassicut...You first have to define the difference between "disciplinced practice" and "practicing playing". Most posters here mistake practicing playing for real practice...which it is not (playing the ghost is not practice...it is practicing playing). For disciplined practice to have the greatest benefit, you have to apply several principles...1) know what you wish to practice, what you can achieve by practicing it, and have a way to measure your results (you can't fix what you can't measure); 2) practice your process, paying specific attention to doing the same thing, the same way, on every shot (make sure the last thing you do is get the tip close to the CB, and stop...before starting your final backswing); 3) practice things that are not too easy, not too hard, and don't take too long (shooting the same shot 200+ times wastes time and effort...you can get more and better feedback, with disciplined practice of maybe 10-20 reps). Lastly, you should always finish up a disciplined practice session with some free play...meaning playing the ghost, an opponent, or just throwing balls out and trying to run them off. So, I would vote for #3, as well! Good luck with your routine. It should only be an hour or two. Of course, you can practice playing 24 hours a day, if you want...but it may or may not result in significant improvement overall.
