how we calculated rating score
max_coefficients = (4.10 * 1 + 3.75 * 1 + 3.50 * 1 + 3.45 * 1) = 14.8
p1 = (0 * 3.65 * 0.86 + 190.48 * 2.60 * 1 + 0 + 0 + 0) / (3.65 * 0.86 + 2.60 * 1 + 1 + 1 + 1) = 56.738823715416835
p2 = (190.48 * 2.60 * 1 + 0 * 3.65 * 0.86) / max_coefficients = 33.46216216216216
score = 56.738823715416835 * 0.5 + 33.46216216216216 * 0.5 = 45.1004929387895
