max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.85
p1 = (569.62 * 3.65 * 1 + 719.10 * 3.75 * 1 + 0 + 0 + 0) / (3.65 * 1 + 3.75 * 1 + 1 + 1 + 1) = 459.2057692307692
p2 = (719.10 * 3.75 * 1 + 569.62 * 3.65 * 1) / max_coefficients = 301.30851735015773
score = 459.2057692307692 * 0.5 + 301.30851735015773 * 0.5 = 380.25714329046343
