max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.85
p1 = (210.53 * 2.10 * 0.86 + 407.41 * 2.30 * 1 + 0 + 0 + 0) / (2.10 * 0.86 + 2.30 * 1 + 1 + 1 + 1) = 185.35023683398805
p2 = (407.41 * 2.30 * 1 + 210.53 * 2.10 * 0.86) / max_coefficients = 83.02649842271293
score = 185.35023683398805 * 0.5 + 83.02649842271293 * 0.5 = 134.18836762835048
