how we calculated rating score
max_coefficients = (4 * 1 + 3.75 * 1 + 4.20 * 0.86 + 2.90 * 1) = 14.249820000000001
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 = 155.82512621212055
score = 264.34285714285716 * 0.5 + 155.82512621212055 * 0.5 = 210.08399167748885
