max_coefficients = (4 * 1 + 3.75 * 1 + 2.90 * 1 + 4.20 * 0.57) = 13.04988
p1 = (466.67 * 1.20 * 0.43 + 482.76 * 3.75 * 1 + 0 + 0 + 0) / (1.20 * 0.43 + 3.75 * 1 + 1 + 1 + 1) = 282.2507819038809
p2 = (482.76 * 3.75 * 1 + 466.67 * 1.20 * 0.43) / max_coefficients = 157.11715356769565
score = 282.2507819038809 * 0.5 + 157.11715356769565 * 0.5 = 219.6839677357883
