max_coefficients = (4.60 * 1 + 4 * 1 + 3.75 * 1 + 3.05 * 1) = 15.399999999999999
p1 = (545.45 * 1.10 * 0.57 + 363.64 * 1.10 * 0.14 + 0 + 0 + 0) / (1.10 * 0.57 + 1.10 * 0.14 + 1 + 1 + 1) = 105.65993877006548
p2 = (545.45 * 1.10 * 0.57 + 363.64 * 1.10 * 0.14) / max_coefficients = 25.974025974025977
score = 105.65993877006548 * 0.5 + 25.974025974025977 * 0.5 = 65.81698237204573
