If lower vacuum is seen for a given speed then you know the WAI is working as pumping losses are being reduced.

I think the goal is to never operate at light loads.

So I'm so confused right now, I thought that you want high vacuum for better efficiency, not to lower the vacuum. And I also thought that you want to lessen the load, which is where weight-reduction and driving slower to make aerodynamic drag lower come in.
