Anyone get BETTER mileage than the trip computer estimate?

I've always heard the MPG readout on a trip computer is wildly optimistic, with the real figures coming in around 1-2 mpg lower than what's indicated. Well, I only have a few fill-ups logged so far, but going by Fuelly's calculations, I'm averaging about 3-4 MPG higher than the trip computer says. The trip computer has been at 17.2 to 17.5 MPG for the last two weeks. I've only seen better than that on long trips, but never in my daily commute.

The figures I'm entering appear to be correct, but something just seems off to me. I wouldn't be too shocked to get 1-2 MPG better. I live in the DFW, TX area, and my miles are at least 80% highway, but it's stop and go a good bit of the time in the afternoon.

If it's true, I'll take it! But like I said, something seems off here.
