And why do I see it all over the place now, especially nba.com. Thanks stat nerds in advance.

There are two of them, the first tracks Glen Davis' in-game snacking. The other is the NBA's attempt at a PER-type number. Roughly speaking the formula is (Points + FG made + FT made - FGA - FTA + dReb + oReb/2 + Asst + Stl + Blk/2 - PF - TO) / (game points + game FG made + game FT made - game FGA - game FTA + game dReb + game oReb/2 + game Asst + game Stl + game blk/2 - game PF - game TO)

NBA.com/stats has developed a new rating called the Player Impact Estimate, or PIE, that calculates a player’s impact on each individual game they play. Because the formula accounts for a player’s influence relative to each specific game, it eliminates statistical biases created by league, style of play or even era.

And now, thanks to PIE, we can make a definitive link between Catchings and James.

The PIE formula compiles everything a single player does in a game -- points scored, rebounds, blocks, missed free throws etc. -- and weighs that number against the same stats generated by everyone in that same game. For the mathematically-minded, the individual player’s stats are the numerator (top) of this equation and the cumulative stats of everyone in the game are the denominator (bottom). The formula then computes a percent value for each player which gives us, in laymen’s terms, the percentage of positive things attributable to that player in that game. Below is the PIE equation.

Luke is too lazy to start game threads. Google is like a marathon for him.
