Scanguage II Calibration: 'Adjustment Factor on Fillup'

Yes, enquiring minds would like to know. I have wondered the same thing...

Here's how I fill my diesel smart normally:

First, I fill at full pump speed until I can hear the fuel starting to come up to the bottom of the filler neck... this is typically when the auto shut off would happen.

Secondly, I typically STOP at this point, and let the 'foam' settle for 10-15 seconds, which probably also allows for more air to escape, and creates more room for fuel.

Thirdly, I fill at a slower rate until the fuel level is right at the top of the filler tube... making sure there is no foam.

Anyway - all of this WAS in an effort to try and be consistent with fills - so I could use the data to show FE of specific 'runs', 'tanks', and the associated gains/losses of tire PSI, tire sizes etc...

At the end of the day, and hence my initial query, I'm looking to use Scanguage to narrow live performance down further... I have a host of possible changes I could make to the car, and I do want to know the effect of each.
