max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (666.67 * 1.20 * 0.14 + 266.67 * 1.20 * 0.29 + 0 + 0 + 0) / (1.20 * 0.14 + 1.20 * 0.29 + 1 + 1 + 1) = 58.54333128457284
p2 = (666.67 * 1.20 * 0.14 + 266.67 * 1.20 * 0.29) / max_coefficients = 15.017518248175183
score = 58.54333128457284 * 0.5 + 15.017518248175183 * 0.5 = 36.78042476637401
