max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.65 * 1 + 4 * 0.86) = 15.5284
p1 = (454.55 * 2.10 * 1 + 565.22 * 2.10 * 1 + 254.90 * 3.05 * 1 + 0 + 0) / (2.10 * 1 + 2.10 * 1 + 3.05 * 1 + 1 + 1) = 315.5632432432432
p2 = (565.22 * 2.10 * 1 + 454.55 * 2.10 * 1 + 254.90 * 3.05 * 1) / max_coefficients = 187.97558022719662
