I assumed by your original argument that the data sampling rate also must be quite slow if it is inaccurate during fast acceleration.
The sampling rate will be much faster than the display. The process will be something like :

counter = 1
:Loop
Take Snapshot
Update Totals
Increase Counter
if Count > Interval Setting then
update display
reset counter = 1
Goto :Loop

The SG2 is good as an instant readout and an estimator of AVG for every day use - I love mine! But not sure it is accurate enough to draw a conclusion here. See MetroMPG's quote from LL earlier.

Best test would be top the tank up, do some slow runs, top it again - repeat a few times. Then repeat it using faster acceleration and compare the amount of fuel used. It would need a large, flat area, a can of fuel, a measuring jug and a some time and patience. It would be very valuable to all though.

I'd give it a go but I can't get Hermann to "brim".
