max_coefficients = (4.10 * 1 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.35
p1 = (933.33 * 1.20 * 1 + 947.37 * 1.90 * 1 + 371.43 * 3.50 * 1 + 0 + 0) / (1.20 * 1 + 1.90 * 1 + 3.50 * 1 + 1 + 1) = 490.69767441860466
p2 = (947.37 * 1.90 * 1 + 371.43 * 3.50 * 1 + 933.33 * 1.20 * 1) / max_coefficients = 274.9185667752443
score = 490.69767441860466 * 0.5 + 274.9185667752443 * 0.5 = 382.8081205969245
