max_coefficients = (4.60 * 1 + 4 * 1 + 3.75 * 0.86 + 3.05 * 1) = 14.864125000000001
p1 = (483.87 * 1.80 * 0.71 + 217.39 * 2.10 * 1 + 0 + 0 + 0) / (1.80 * 0.71 + 2.10 * 1 + 1 + 1 + 1) = 168.91542718619925
p2 = (483.87 * 1.80 * 0.71 + 217.39 * 2.10 * 1) / max_coefficients = 72.56733914710755
score = 168.91542718619925 * 0.5 + 72.56733914710755 * 0.5 = 120.7413831666534
