max_coefficients = (4.20 * 1 + 4 * 1 + 3.75 * 1 + 2.80 * 1) = 14.75
p1 = (816.09 * 3.75 * 1 + 466.67 * 4.20 * 1 + 841.12 * 4 * 1 + 0 + 0) / (3.75 * 1 + 4.20 * 1 + 4 * 1 + 1 + 1) = 601.063082437276
p2 = (841.12 * 4 * 1 + 816.09 * 3.75 * 1 + 466.67 * 4.20 * 1) / max_coefficients = 568.4630508474576
score = 601.063082437276 * 0.5 + 568.4630508474576 * 0.5 = 584.7630666423668
