how we calculated rating score
max_coefficients = (4.05 * 1 + 3.50 * 1 + 3.45 * 1 + 3.30 * 1) = 14.3
p1 = (666.67 * 1.20 * 1 + 400 * 3.30 * 1 + 266.67 * 1.20 * 1 + 0 + 0) / (1.20 * 1 + 3.30 * 1 + 1.20 * 1 + 1 + 1) = 316.8831168831169
p2 = (400 * 3.30 * 1 + 666.67 * 1.20 * 1 + 266.67 * 1.20 * 1) / max_coefficients = 170.6293706293706
score = 316.8831168831169 * 0.5 + 170.6293706293706 * 0.5 = 243.75624375624375
