how we calculated rating score
max_coefficients = (4.20 * 1 + 4.05 * 1 + 3.50 * 1 + 3.45 * 1) = 15.2
p1 = (0 * 1.20 * 0.14 + 1000 * 1.20 * 1 + 363.64 * 1.10 * 1 + 0 + 0) / (1.20 * 0.14 + 1.20 * 1 + 1.10 * 1 + 1 + 1) = 357.82336049809015
p2 = (1000 * 1.20 * 1 + 363.64 * 1.10 * 1 + 0 * 1.20 * 0.14) / max_coefficients = 105.26315789473685
score = 357.82336049809015 * 0.5 + 105.26315789473685 * 0.5 = 231.5432591964135
