With their payroll if the Cubs fail to contend in a league this crummy then Hendry should be shot out of a cannon Do you honestly believe every single one of those predictions and believe there will not be one single 90-win team in the whole darn league? Also, if I'm not mistaken most predictions gravitate toward the mean. It's not surprising that no team has an excessive amount of wins. Do they use pythagorean wins based on RS/RA? This would account for the lack of outliers. IIRC, the Cubs often underachieve relative to pythagorean predictions Close. They use pythaganport with AEqR and AEqRA Pythaganport - A modified form of Bill James' pythagorean formula. Instead of using a fixed exponent (2, 1.83), the "pythagenport" formula derives the exponent from the run environment - the more runs per game, the higher the exponent. The formula for the exponent was X = .45 + 1.5 * log10 ((rs+ra)/g), and then winning percentage is calculated as (rs^x)/(rs^x + ra^x). The formula has been tested for run environments between 4 and 40 runs per game, but breaks down below 4 rpg. AEqR -The number of equivalent runs scored by a team, adjusted for the quality of their opponent's pitching and defense. AEqRA - The number of equivalent runs allowed by a team, adjusted for the quality of their opponent's offense.
