Don't forget dry breaks, unless you're only counting times you're at the table shooting after the break, or you're playing 9 ball with a magic rack.I think if I put up % of why I did not run out a rack, I'd list
40% miss a shot I lined up for
25% hooked myself - often by 1mm
20% misplayed shape and missed a tough shot or made it but no shape on next ball which ends up in some good shots but most often a loss
15% messed up a safe
