This function returns the same value as Pk, but with Rall power sets to 2
Metric Total_Sum #Compartments
(considered)		 #Compartments

Pk_2 154 96 (1458) 0.18 1.64727 2 0.44015

In the above example the total sum of the Pk_2 ratio doesn't make sense. Only the compartments leading to bifurcation are considered, 96 according to this example.

All other compartments are discarded, 1458 according to this example.

The minimum value returns the minimum Pk_2 ratio value, 0.18 in this example.

The average returns the average Pk_2 ratio value, 1.64 in this example.

The maximum returns the maximum Pk_2 ratio value, 2 in this example.

The S.D is 0.44
