Baseball Pythagorean Expectation Calculator
Calculate expected wins based on runs scored and allowed using Bill James' Pythagorean formula
About Pythagorean Expectation
Pythagorean Expectation, developed by Bill James, predicts a team's expected winning percentage based on runs. The formula is: Win% = RS^exp / (RS^exp + RA^exp). The original exponent was 2, but 1.83 (Pythagenpat) is more accurate. Teams that significantly outperform their Pythagorean record often regress the following season.
