The perception of how often a Pro wins a game without the other person shooting is higher than the reality.
I'm not sure what your statement means, nor am I clear on what numbers you are pointing to from Pool-Trax to support your statement. Maybe you could explain that a little more.
The only time one player wins without the other player having an inning (including a return on a push-out) is on break-and-run games. The link you provided shows stats for Shane for 39 of his matches tracked by Pool-Trax. It shows a B&R of nearly 40%, but nearly half of those breaks were on 3½x7 tables (where his B&R was 47%).
I posted some information recently showing how many streamed games in an event were won by the breaker and non-breaker in 1, 2, 3, etc. innings. Here's that post for the CSI Invitational 10-Ball Championship 3 months ago: http://forums.azbilliards.com/showpost.php?p=4818728&postcount=8
Within the next few days, I'll try to do something similar for the just-concluded U.S. Open 9-Ball Championship.
