Although not a direct control variable, the 'health' of the system can be gauged by the consistency of relative 'stagger' (or difference) between these three parameters at any single point in time. A-B, B-C, C-A.
I am struggling to find an effective way to represent these relative stagger values - on the same timeline. A simple plot of e.g. A - B cycles positive to negative but isn't very intuitive. Ideally I'd like to represent all three relative differences on one discernible plot.
