p1 = (747.66 * 4 * 1 + 1000 * 1.80 * 1 + 391.30 * 1.40 * 1 + 0 + 0) / (4 * 1 + 1.80 * 1 + 1.40 * 1 + 1 + 1) = 580.2695652173913
p2 = (747.66 * 4 * 1 + 1000 * 1.80 * 1 + 391.30 * 1.40 * 1) / max_coefficients = 374.63490766900907
score = 580.2695652173913 * 0.5 + 374.63490766900907 * 0.5 = 477.4522364432002
