Calibration is probaby for psychological reasons, people like to see their mileage gauge moving, so they know it's 'working'.
This analysis is right on. That guage moves constantly really. On the pedal, it floors the guage all the way to the right, if you're even slightly on the go pedal, you're down under 20MPG real quick, off the pedal, the guage pegs left. It's really useless IMHO. The 350Z also has a three guage set, I wonder if they have something better in the leftmost guage. The water temp guage already exists in the driver's side guage cluster so that'd be a repeat. Oil temp maybe, though I'm not sure how useful that'd be.
I get the feeling this feature wasn't real well thought out and they ended up throwing the MPG guage in there because the CPU already tracked the data so it was a shoe in. Perhaps an analog clock is another option, though that'd be too luxury oriented for a car like this since the radio already displays time.
