Pythagorean Exponent, x 1 Notice PS and PA replace RS and RA but have the same meaning. b = 0.50, (5) m = [n(PS PA)W% 0] / [n(PS PA)2 0] For games played without fans in attendance, home-field advantage is worth 9.6 rating points.

(Equation 4), For the NBA, EXP (W%) = [(PS PA)W% / [2850.8(PS PA)W% 673,540]]*(PS PA) + 0.50. The Linear Formula for NFL Football is EXP (W%) = 0.001538(PS PA) + 0.50.
