how we calculated rating score
max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (304.35 * 1.40 * 1 + 448.60 * 4 * 1 + 391.30 * 2.10 * 1 + 0 + 0) / (1.40 * 1 + 4 * 1 + 2.10 * 1 + 1 + 1) = 320.23368421052635
p2 = (448.60 * 4 * 1 + 391.30 * 2.10 * 1 + 304.35 * 1.40 * 1) / max_coefficients = 222.05985401459853
score = 320.23368421052635 * 0.5 + 222.05985401459853 * 0.5 = 271.1467691125624
