How does Accu-Stats’ TPA player rating system work?
The Tournament Performance Average (TPA) can be used to measure a player’s performance in a match or tournament. It is a single number (like a batting average) based on the following formula:
TPA = (# of Balls Made) / (# of Balls Made + # of Errors)
Errors are any of the following:
- missing a shot
- getting out of position
- missing a kick
- scratching on the break
- failing to execute a safety successfully
For example, if you make 100 balls in a match and commit 25 errors, your TPA would be 0.800 (100/125) or 800 (100/125*1000). A perfect score, with no errors, would be 1.000 or 1000. A TPA above 850 over a long match is considered pro level, and TPAs above 900 are considered world class.
