max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (207.21 * 4.05 * 0.29 + 65.42 * 4 * 1 + 0 + 0 + 0) / (4.05 * 0.29 + 4 * 1 + 1 + 1 + 1) = 61.47294039476112
p2 = (65.42 * 4 * 1 + 207.21 * 4.05 * 0.29) / max_coefficients = 36.60145985401459
score = 61.47294039476112 * 0.5 + 36.60145985401459 * 0.5 = 49.03720012438785
