max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (210.53 * 2.10 * 1 + 407.41 * 2.30 * 1 + 0 + 0 + 0) / (2.10 * 1 + 2.30 * 1 + 1 + 1 + 1) = 186.3716216216216
p2 = (407.41 * 2.30 * 1 + 210.53 * 2.10 * 1) / max_coefficients = 100.66788321167883
score = 186.3716216216216 * 0.5 + 100.66788321167883 * 0.5 = 143.51975241665022
