LastTwo said:That's nonsense. What determines a winning percentage is how well the table in particular is breaking. When guys are running 5 and 6 packs, how does Pat Flemming's percentage figure in? Sinking a ball and getting position on the lowest numbered ball is not the only advantage from the break. Another huge advantage is having control of the table. If you've got no shot, play a good safe, or push out to something you might fire in, but your opponent might not be the favorite to make. That's pretty ideal, but it's another advantage.
I'm very familiar with Pat's analysis, done more than ten years ago, and have discussed it with him. He did indicate that the breaking player won just over 52% of the racks. It should be noted, however, that the analysis was based on play observed on tight equipment (meaning 4 1/2 inch corners). In the same analysis, Pat determined that "a pro in dead stroke" (his words, not mine) will break and run roughly three out of every ten racks.
Pat agreed that on even slightly looser equipment, the break becomes a significant advantage in men's pro pool.
