Standard Deviation of Efficiency Differential

This may sound like something from a math class but the basic principle is relatively easy. Teams that play more erratic from game to game are likely to play closer to .500 than they should. A team over .500 will be dragged back down by erratic play, where a poor team under .500 will have a better record than they should. How erratic a team is can be determined by looking at the standard deviation of their offensive and deffensive efficiency differentials from each game. A team with a higher standard deviation has played in a games with a wider range of point differentials, and is tougher to handicap. A team with a low standard deviation is very consitent and should be easier to judge.
