How to view pool member rank used by predictive LB method

When we choose predictive LB method, F5 uses dynamic LB algorithm which ranks pool member performance over time and prefers pool members that exhibit an improvement in performance over those that exhibit a decline. My question is: does anybody know how can I view current rank (or score) of a pool member?

The following command: (tmsh) list /ltm node all-properties

returns an option called "dynamic-ratio", which is some ration based on continuous monitoring of the servers and, according to TMSH Reference manual, continually changing. But it always show the default value - 1.
