max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (333.33 * 1.80 * 0.43 + 521.74 * 2.10 * 1 + 0 + 0 + 0) / (1.80 * 0.43 + 2.10 * 1 + 1 + 1 + 1) = 230.4035779735263
p2 = (521.74 * 2.10 * 1 + 333.33 * 1.80 * 0.43) / max_coefficients = 98.74525547445256
score = 230.4035779735263 * 0.5 + 98.74525547445256 * 0.5 = 164.57441672398943
