max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (666.67 * 1.80 * 0.43 + 290.32 * 1.80 * 0.86 + 0 + 0 + 0) / (1.80 * 0.43 + 1.80 * 0.86 + 1 + 1 + 1) = 181.0637793408678
p2 = (666.67 * 1.80 * 0.43 + 290.32 * 1.80 * 0.86) / max_coefficients = 70.23503649635036
score = 181.0637793408678 * 0.5 + 70.23503649635036 * 0.5 = 125.64940791860909
