Also, I think it would be nice if the queries could be abstracted so it was easy to switch between the standard ReigsterPressureTracker and the improved version you have implemented.


It is not a tracker, just the estimation. It least not just yet. During scheduling standard RPTracker still used for pressure diffs.
