max_coefficients = (4 * 1 + 3.75 * 1 + 4.20 * 0.71 + 2.90 * 1) = 13.650060000000002
p1 = (200 * 1 * 1 + 818.18 * 1.10 * 0.57 + 1000 * 1.10 * 1 + 0 + 0) / (1 * 1 + 1.10 * 0.57 + 1.10 * 1 + 1 + 1) = 383.6829126960964
p2 = (1000 * 1.10 * 1 + 818.18 * 1.10 * 0.57 + 200 * 1 * 1) / max_coefficients = 132.91223628321046
score = 383.6829126960964 * 0.5 + 132.91223628321046 * 0.5 = 258.29757448965347
