sci.Pythagorean-expectation-sport Calculator
Calculates the Pythagorean win expectation from runs/goals scored and allowed: Win% = RS^2/(RS^2+RA^2), originally derived for baseball. Pythagorean expectation predicts end-of-season win% better than actual win% early in a season — NFL exponent ≈ 2.37; NBA ≈ 13.9 (reflecting the lower run of scoring variability).
