Why does the command duration go sky high at low load and high rpm? Is it part of the rpm limiter?

It just doesn't seem proportional, even thou flow decreases with a pressure decrease.

To obtain the referenced mm3 at less pressure it takes more duration.

The lower the pressure the less fuel going through injector. In order to obtain the commanded volume of fuel at lower pressures the duration must go up.

Which makes sense, but it just seems disproportionate to the actual time it would be needed to inject.
