how we calculated rating score
max_coefficients = (4.60 * 1 + 4 * 1 + 3.65 * 1 + 3.05 * 1) = 15.3
p1 = (315.79 * 2.10 * 1 + 185.19 * 2.30 * 1 + 0 + 0 + 0) / (2.10 * 1 + 2.30 * 1 + 1 + 1 + 1) = 147.17432432432432
p2 = (315.79 * 2.10 * 1 + 185.19 * 2.30 * 1) / max_coefficients = 71.18235294117646
score = 147.17432432432432 * 0.5 + 71.18235294117646 * 0.5 = 109.17833863275038
