You are spot on. I drive a small yet peppy 2.0 lt turbo car and mileage varies greatly depending on my driving habits, much more than other fuel injected vehicles I've owned.
IMO the question is how should they test these cars to get a reasonable result. When I just bought my car I was on the boost most of the time (enjoying it), and now much less. The issue at hand is that the same car/driver may get very different results at different points.
