max_coefficients = (4.60 * 1 + 4 * 1 + 3.75 * 1 + 3.05 * 1) = 15.399999999999999
p1 = (956.52 * 2.10 * 1 + 58.82 * 3.05 * 1 + 645.16 * 1.80 * 1 + 0 + 0) / (2.10 * 1 + 3.05 * 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 = 217.4935064935065
score = 374.2346368715084 * 0.5 + 217.4935064935065 * 0.5 = 295.8640716825075
