<!--quoteo-->QUOTE <!--quotec-->A player gets credit (a "plus" number) if he makes a play that at least one other player at his position missed during the season, and he loses credit (a "minus" number) if he misses a play that at least one player made. The size of the credit is directly related to how often players make the play. Each play is looked at individually, and a score is given for each play. Sum up all the plays for each player at his position and you get his total plus/minus for the season.<!--QuoteEnd--><!--QuoteEEnd-->

Until a read that closely, I thought +/- was a fairly straight forward rasonably acurate stat. It should be zero= average, +1 above average, -1 below average. Not only is a negative any play that the best player would make and a positive would be any play that the worst player could not make (which is convoluted) but a second judgment is made, giving each play a score.

Each play is one event. With that system a player can get to much credit/penalty for one play. It would be like getting 2 or 3 hits for a particularly well hit ball. Since there are 2 judgements on each play and each judgement has a given margin of error, it increases the total margin of error.
