max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (58.82 * 3.05 * 1 + 956.52 * 2.10 * 1 + 0 + 0 + 0) / (3.05 * 1 + 2.10 * 1 + 1 + 1 + 1) = 268.479754601227
p2 = (956.52 * 2.10 * 1 + 58.82 * 3.05 * 1) / max_coefficients = 159.71605839416057
score = 268.479754601227 * 0.5 + 159.71605839416057 * 0.5 = 214.09790649769377
