As to Accu-Stats not counting a dry break as an error in the TPA -- with some breaking conditions/rules, where the break becomes a real skill shot with dead balls if hit properly, you have a point. But under other conditions/rules, making a ball is still pretty much fluky no matter how the player breaks, so it would be tough to say the breaker erred. [I'm not aware of A-S doing any TPA's for 8-Ball.]
