p1 = (466.67 * 4.20 * 0.43 + 816.09 * 3.75 * 1 + 841.12 * 4 * 1 + 0 + 0) / (4.20 * 0.43 + 3.75 * 1 + 4 * 1 + 1 + 1) = 628.9882702517376
p2 = (841.12 * 4 * 1 + 816.09 * 3.75 * 1 + 466.67 * 4.20 * 0.43) / max_coefficients = 530.2839416058393
score = 628.9882702517376 * 0.5 + 530.2839416058393 * 0.5 = 579.6361059287885
