There is a LOT of diagnostics going on behind the scenes and it is my belief that most of this is only provided on a need to know basis.
The pump can move to near capacity, but not full capacity. Additionally, it is controlled by a complicated set of PIDs, expected flow rates, flow limits, etc. These are based on small errors and large errors both positive and negative. These are likely there to provide a smoothing effect to prevent the pressures from spiking and sagging. I will not claim that I can even begin to understand the entire interworkings of these tables, but wheat I will say is that I have had solid success in tuning to help the pump stay on target.
So basically you joined the forum to call BS on me...
