It's what you registered of course.
The only question is what the experimental error on that measurement is

The smaller the values you register (fuel quantity and miles driven) the higher the error will be.
The fuel pump cut-off will introduce the biggest - unknown - variable.

I did run into a problem concerning the theory of testing:

So I guess what I mean is...with a scanguage, how do you know the moment is right to take a readout?
The instant readings don't get used.
The recording is started (i.e. SG trip is reset) at a fixed point along the route.
The reading taken is the recorded average, again read out at a fixed point along the route (say an exit sign).

Even then, as with any road-side testing, there'll always be errors due to conditions beyond the control of the tester or his equipment.
