Wondering what the voltage drop is on the load switches of the QPM. Wouldn't it be cool if you could use that as input to the INA3221, and kill two birds with one stone (removing the need for the 0.1R shunt). You could then switch loads AND measure their parameters at the same time.

Interesting idea. Trouble is each will vary a bit (more than the 0.1 ohm resistor) and it I can't see that it would be linear in any case since it is related to diode drops.
