how we calculated rating score
max_coefficients = (4.10 * 1 + 3.85 * 1 + 3.75 * 1 + 3.50 * 1) = 15.2
p1 = (600 * 1.20 * 1 + 526.32 * 1.90 * 1 + 0 + 0 + 0) / (1.20 * 1 + 1.90 * 1 + 1 + 1 + 1) = 281.9672131147541
p2 = (526.32 * 1.90 * 1 + 600 * 1.20 * 1) / max_coefficients = 113.15789473684211
score = 281.9672131147541 * 0.5 + 113.15789473684211 * 0.5 = 197.5625539257981
