max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (466.67 * 1.20 * 0.29 + 560 * 4.20 * 0.57 + 0 + 0 + 0) / (1.20 * 0.29 + 4.20 * 0.57 + 1 + 1 + 1) = 261.8828708347264
p2 = (560 * 4.20 * 0.57 + 466.67 * 1.20 * 0.29) / max_coefficients = 109.77518248175183
score = 261.8828708347264 * 0.5 + 109.77518248175183 * 0.5 = 185.82902665823912
