max_coefficients = (4.10 * 1 + 3.85 * 1 + 3.75 * 1 + 3.50 * 1) = 15.2
p1 = (383.18 * 4.60 * 0.71 + 522.39 * 4.10 * 1 + 0 + 0 + 0) / (4.60 * 0.71 + 4.10 * 1 + 1 + 1 + 1) = 327.45061035377216
p2 = (522.39 * 4.10 * 1 + 383.18 * 4.60 * 0.71) / max_coefficients = 223.73881578947368
score = 327.45061035377216 * 0.5 + 223.73881578947368 * 0.5 = 275.5947130716229
