how we calculated rating score
max_coefficients = (4.05 * 1 + 3.50 * 1 + 3.45 * 1 + 3.30 * 1) = 14.3
p1 = (600 * 3.30 * 1 + 343.28 * 3.50 * 1 + 200 * 1.20 * 1 + 0 + 0) / (3.30 * 1 + 3.50 * 1 + 1.20 * 1 + 1 + 1) = 342.149
p2 = (600 * 3.30 * 1 + 343.28 * 3.50 * 1 + 200 * 1.20 * 1) / max_coefficients = 239.26503496503494
