max_coefficients = (4.60 * 1 + 4 * 1 + 3.85 * 1 + 3.65 * 1) = 16.099999999999998
p1 = (608.70 * 1.40 * 0.57 + 9.35 * 4 * 1 + 0 + 0 + 0) / (1.40 * 0.57 + 4 * 1 + 1 + 1 + 1) = 67.2195754850025
p2 = (608.70 * 1.40 * 0.57 + 9.35 * 4 * 1) / max_coefficients = 32.56583850931678
score = 67.2195754850025 * 0.5 + 32.56583850931678 * 0.5 = 49.892706997159635
