I'm just curious on what you all believe: how much of a percentage advantage is there to having the table open if a ball is made on an 8-ball rack compared to having to 'take what you make'? 10% better chance of running out or a 50% better chance of running out? I'm thinking the odds are closer to 33%. I've played both BCA and APA rules. Running out is much easier when open if you make a ball. (This is a math question...NOT a rules preference question.) Thanks all. What do you think?
