Real life fuel economy

I have submitted the life-time petrol comsumption of our Ampera three times now (most recently, a few minutes ago), but it does not appear in your results (which are still showing only three submissions). Am I doing something wrong?

After just over 8,500 miles in 10 months, the display shows a lifetime comsumption of 211 mpg. We put it on charge every night, and most daily journeys, in very hilly Devon counrtyside, are less than the average 40 mile battery range.

If you are putting in 211mpg then the system would reject that as too great a disparity from the average 76.1mpg because you are obviously running it mostly on plug-in electricity and will also be benefiting from regeneration on the downhill stretches of the hilly terrain. Plug-in hybrid use is different from average use because a lot of it is on power station electricity rather than internal combustion engine, but our system has to have checks and balances based on the way most people run a car and 99.99% of cars are still internal combustion.
