max_coefficients = (4 * 1 + 3.75 * 1 + 4.20 * 0.71 + 2.90 * 1) = 13.650060000000002
p1 = (818.18 * 1.10 * 0.86 + 545.45 * 1.10 * 0.43 + 0 + 0 + 0) / (1.10 * 0.86 + 1.10 * 0.43 + 1 + 1 + 1) = 233.00568383900395
p2 = (818.18 * 1.10 * 0.86 + 545.45 * 1.10 * 0.43) / max_coefficients = 75.35131713706751
score = 233.00568383900395 * 0.5 + 75.35131713706751 * 0.5 = 154.17850048803572
