I've been doing Joe Tuckers Guaranteed Improvement workbook for a few months. One of his drills is the 10 ball ghost. Each session is 10 total games. I probably have close to 10 sessions as of now. In all that time, I think I average ONE ball on the break about 20% of the time. Joe's particular score system penalizes you for scratching on the break, so my break is very controlled like a gambling session.
So I am playing 10 ball with 10 balls on the table 80% of the time. In 9 ball I am probably playing with 7 to 8 balls on the table 50% of the time.
