I was watching a U.S. Open 9-Ball match and the announcers said a player had a Performance Rating of 941 and that this indicated that his level of play was world-class.

How is this performance rating calculated?

Thanks. /ccboard/images/graemlins/cool.gif

Haven't checked it out yet. I just received this reply from Accu-Stats:

"The instructions for scorekeeping is in the "LIBRARY" of our website, accu-stats.com. Basically, it's like a batting avg in baseball. Everytime a player pockets a ball, it's like a hit in baseball, everytime a player makes an mistake, it's like striking out.

The formula for the TPA is:

(Balls Pocketed + Errors)
