To calculate the D(Pts) take the actual points earned - E(Pts)Īn example at this point may be helpful, and for that we'll look at my team, the Olentangy Braves to date, we are 4-2-2 and have scored 22 goals and given up 13 so our calculations are as follows POINTS = 14 (where points = 4 wins * 3 points/win + 2 ties * 1 point/tie = 14) To calculate the E(Pts) or expected points, take the total number of games played * 3 points/game * the Pythagorean score. Pythagorean score = (GF * GF) / ((GF*GF) + (GA*GA)) To calculate the pythagorean score, you need to know the following: The total possible points a team can gain is 3 * the number of games played. Some things to keep in mind for purposes of this discussion: I'll do my best to explain what they mean.Į(Pts) - is the expected # of points a team should have (based on their Pythagorean score)ĭ(Pts) - is the difference between the # of points they actually have and their expected points. In fact they are something that I used on my own personal site ( and the OSSCA guys ported over to their site when we combined data(bases). From Dave Sebek - OSSCA Web Team and Statistic Leadįirst off, we do not use any of those numbers for any sort of auto-ranking.
