how we calculated rating score
max_coefficients = (4 * 1 + 3.75 * 1 + 2.90 * 1 + 4.20 * 0.57) = 13.04988
p1 = (304.35 * 1.40 * 1 + 448.60 * 4 * 1 + 0 + 0 + 0) / (1.40 * 1 + 4 * 1 + 1 + 1 + 1) = 264.34285714285716
p2 = (448.60 * 4 * 1 + 304.35 * 1.40 * 1) / max_coefficients = 170.15328876587373
score = 264.34285714285716 * 0.5 + 170.15328876587373 * 0.5 = 217.24807295436545
