how we calculated rating score
max_coefficients = (4 * 1 + 3.75 * 1 + 4.20 * 0.71 + 2.90 * 1) = 13.650060000000002
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 = 162.67181243159368
score = 264.34285714285716 * 0.5 + 162.67181243159368 * 0.5 = 213.50733478722543
