The greater the ratio of priority to subordinates, the greater the gains (losses) obtained by subordinates.

For example, if the total rate of return is 10% and the priority rate of return is 8%, then suppose that the ratio of priority to secondary is 2: 1, which is twice, and the secondary rate of return is 10%*3-8%*2= 14%. If the ratio is enlarged to 3: 1, the inferior rate of return is 16%.

If the total rate of return is 6% and the priority rate of return is 8%, the inferior rate of return is 2%. If the ratio is 3: 1, the rate of return after inferiority is 0%.
