i'd surmise that the number is within 15% of the real value.
what do others think?
Number of starts and acceleration, metabolic efficiency, temperature. And wind resistance implies a lot of variables which are very dependent on the individual.
The calculation is around 25% higher than I expected, reasonable but enough error term there that you may not have a clear result comparing to fuel costs.
