fits my experience, too.
for my 4mi commute between home and the train station, average speed in suburbia is 18mph (lots of lights on average) with 24-25mpg reported by the computer. mixed in with some weekend driving which involves longer stints and short stretches of freeway (so not optimal for mileage because of the need to accelerate to 65mph and only drive it for 4-5miles), it boosts me into the 29mpg range on the computer. in the end, my cars lifetime computer mileage is 29.4mpg* at an average speed of about 26mph.
* which is i know optimistic, even with odometer errors accounted for. it actually is closer to 28.5 when everything is accounted for.
