In the Cue the Experts episode "Why You're Practicing Too Long" (Season 2, Episode 6) ---
--- , Roy Pastor explains, starting at the 47:55 mark, that for efficient pool practice one should only strive for 30 minutes of practice at a time, mentioning that Efren Reyes suggested this as well. This raises the question: does this mean 30 minutes for each skill you want to work on, or just 30 minutes on one single skill for the day? The best players in the world clearly practice more than 30 minutes a day. Willie Mosconi, for example, would often practice for short periods, take a coffee break, and then go right back to the table. It seems Pastor is actually suggesting 30-minute blocks with breaks for each specific skill, like shot-making, position drills, and breaking. This also leaves open the question of how playing the ghost or playing 14.1 for a personal high run fits into this practice, especially since it is easy to spend hours playing 14.1. The best way to reconcile this is that the 30-minute rule applies strictly to repetitive, isolated drills where mental focus quickly fades, while open-ended application games like straight pool are meant to be played for hours to build your overall table stamina. What are your thoughts on this?
