how we calculated rating score
max_coefficients = (4.71 * 1 + 3.90 * 1 + 3.40 * 1 + 3.40 * 1) = 15.41
p1 = (909.09 * 1.10 * 0.86 + 259.26 * 2.45 * 1 + 0 + 0 + 0) / (1.10 * 0.86 + 2.45 * 1 + 1 + 1 + 1) = 233.43255939094072
p2 = (909.09 * 1.10 * 0.86 + 259.26 * 2.45 * 1) / max_coefficients = 96.83906554185593
score = 233.43255939094072 * 0.5 + 96.83906554185593 * 0.5 = 165.13581246639833
