max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (363.64 * 1.10 * 0.29 + 545.45 * 1.10 * 0.71 + 0 + 0 + 0) / (1.10 * 0.29 + 1.10 * 0.71 + 1 + 1 + 1) = 132.4048780487805
p2 = (545.45 * 1.10 * 0.71 + 363.64 * 1.10 * 0.29) / max_coefficients = 39.62481751824817
score = 132.4048780487805 * 0.5 + 39.62481751824817 * 0.5 = 86.01484778351433
