max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.65 * 1 + 4 * 0.86) = 15.5284
p1 = (28.04 * 4 * 0.86 + 806.45 * 1.80 * 1 + 0 + 0 + 0) / (4 * 0.86 + 1.80 * 1 + 1 + 1 + 1) = 188.09610616887852
p2 = (806.45 * 1.80 * 1 + 28.04 * 4 * 0.86) / max_coefficients = 99.67092552999665
score = 188.09610616887852 * 0.5 + 99.67092552999665 * 0.5 = 143.88351584943757
