VP Dynamic Timing Vs. Advancing

The VP44 pump as we all know has dynamic timing. This means that injection timing advances or retards based on Engine RPM, and load. Obviously there are limitations to the range in which the pump can operate.

So, what I want to know is...

If you advance timing through the use of a timing box, i.e. an edge comp, edge ez, power puck, smarty etc... Are you just advancing the low end timing? In effect bringing it closer to the timing at full advance, and decreasing the function of your dynamic timing, or does it extend the entire range of the dynamic timing?

Just curious if anyone has thought about this, or knows the answer. Thanks,
Sean
