p1 = (466.67 * 4.20 * 0.57 + 816.09 * 3.75 * 1 + 841.12 * 4 * 1 + 0 + 0) / (4.20 * 0.57 + 3.75 * 1 + 4 * 1 + 1 + 1) = 620.9748573648465
p2 = (841.12 * 4 * 1 + 816.09 * 3.75 * 1 + 466.67 * 4.20 * 0.57) / max_coefficients = 578.1486113282268
score = 620.9748573648465 * 0.5 + 578.1486113282268 * 0.5 = 599.5617343465367
