max_coefficients = (4.20 * 1 + 4.05 * 1 + 2.80 * 1 + 3.50 * 0.71) = 13.55005
p1 = (871.79 * 1.80 * 1 + 645.16 * 1.80 * 1 + 0 + 0 + 0) / (1.80 * 1 + 1.80 * 1 + 1 + 1 + 1) = 413.71515151515155
p2 = (871.79 * 1.80 * 1 + 645.16 * 1.80 * 1) / max_coefficients = 201.51364755111604
score = 413.71515151515155 * 0.5 + 201.51364755111604 * 0.5 = 307.6143995331338
