max_coefficients = (4.60 * 1 + 4 * 1 + 3.75 * 1 + 3.05 * 1) = 15.399999999999999
p1 = (727.27 * 2.10 * 1 + 347.83 * 2.10 * 1 + 0 + 0 + 0) / (2.10 * 1 + 2.10 * 1 + 1 + 1 + 1) = 313.5694444444444
p2 = (727.27 * 2.10 * 1 + 347.83 * 2.10 * 1) / max_coefficients = 146.60389610389612
score = 313.5694444444444 * 0.5 + 146.60389610389612 * 0.5 = 230.08667027417027
