max_coefficients = (4.20 * 1 + 4 * 1 + 3.75 * 1 + 2.80 * 1) = 14.75
p1 = (368.42 * 2.10 * 1 + 678.16 * 3.75 * 1 + 252.34 * 4 * 1 + 0 + 0) / (2.10 * 1 + 3.75 * 1 + 4 * 1 + 1 + 1) = 365.07426160337553
p2 = (678.16 * 3.75 * 1 + 252.34 * 4 * 1 + 368.42 * 2.10 * 1) / max_coefficients = 293.29694915254237
