max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (600 * 1.20 * 0.29 + 666.67 * 3.75 * 1 + 533.33 * 1.20 * 1 + 0 + 0) / (1.20 * 0.29 + 3.75 * 1 + 1.20 * 1 + 1 + 1) = 458.76503529489196
p2 = (666.67 * 3.75 * 1 + 533.33 * 1.20 * 1 + 600 * 1.20 * 0.29) / max_coefficients = 244.21167883211675
score = 458.76503529489196 * 0.5 + 244.21167883211675 * 0.5 = 351.48835706350434
