max_coefficients = (4.60 * 1 + 4 * 1 + 3.65 * 1 + 3.05 * 1) = 15.3
p1 = (560 * 4.20 * 0.29 + 168.22 * 4.60 * 1 + 0 + 0 + 0) / (4.20 * 0.29 + 4.60 * 1 + 1 + 1 + 1) = 164.29657474937332
p2 = (168.22 * 4.60 * 1 + 560 * 4.20 * 0.29) / max_coefficients = 94.4967320261438
score = 164.29657474937332 * 0.5 + 94.4967320261438 * 0.5 = 129.39665338775856
