The 6-8 Performance Indicator (+/-) was designed by Tony & Maggie as a way to evaluate athlete performance through game statistics. The PI is a weighted formula of stats that calculates the impact a player has on a game. We use the stats either collected through the individual game scoring feature on the 6-8 Sports App or through the 6-8 game desk iPad app (for teams/ individuals).
The higher your PI score, the more positive impact you had on the game. Please check out THIS PAGE (scroll down) to find out the range of PI scores centers/ defenders, attackers/ goalies and defensive attackers.
