We are talking 1p here, right? What kind of shot in 1p comes up where you manage to bounce the object ball off table and at the same time keep the cue ball on table? Who shoots that hard when they try to move or make a ball in 1p?.
Well, its definately not a planned shot, but sometimes when you are trying to clear balls or something, an OB will catch the rail wrong and spit off the table. Even trying to jump the ball out of the pocket sometimes has some funny consequences... I've had both balls fly off, only the OB fly off and even just the CB go airborne.
