max_coefficients = (4.71 * 1 + 3.90 * 1 + 4.10 * 0.86 + 3.45 * 1) = 15.574109999999997
p1 = (909.09 * 0.90 * 0.43 + 433.57 * 4.71 * 1 + 0 + 0 + 0) / (0.90 * 0.43 + 4.71 * 1 + 1 + 1 + 1) = 295.5591459211882
p2 = (433.57 * 4.71 * 1 + 909.09 * 0.90 * 0.43) / max_coefficients = 153.63767175138742
score = 295.5591459211882 * 0.5 + 153.63767175138742 * 0.5 = 224.5984088362878
