max_coefficients = (4.60 * 1 + 4 * 1 + 3.85 * 1 + 3.65 * 1) = 16.099999999999998
p1 = (58.82 * 3.05 * 1 + 956.52 * 2.10 * 1 + 645.16 * 1.80 * 1 + 0 + 0) / (3.05 * 1 + 2.10 * 1 + 1.80 * 1 + 1 + 1) = 374.2346368715084
p2 = (956.52 * 2.10 * 1 + 645.16 * 1.80 * 1 + 58.82 * 3.05 * 1) / max_coefficients = 208.03726708074535
score = 374.2346368715084 * 0.5 + 208.03726708074535 * 0.5 = 291.1359519761269
