A Player - Break and run 3-4 out of every 5 racks? That sounds like a pro level player to me. What does a pro player break and run by your definition - 9 out of every 10 racks?
Chris, if you're referring to me and my once-in-a-lifetime best story of breaking and running two racks in a row and then making 8-ball on third rack, are you serious? That isn't the norm! I can occasionally play pretty good but it was best ever. It's like my friend who legitimately shot 67 on the golf course one day. I saw him do it but it is not the norm. He's a decent player but ten shots higher on his good days. He strutted around like a peacock for a week. Good for him, I patted him on the back often and he ate it up. Why shouldn't he, it was best he ever shot in decades of golf.
EDIT: Oh wait, my bad, you are referring to the other post where the rankings are described. Sorry!
