For those that are in to it, the Prius community has an excellent fuel consumtion spreadsheet, made by one of there members. And its my favourite price. Free.
It is set up so that it can be used for any vehicle. I have it set for three of mine, including Henrietta Honda.
It can indicate avg fuel consumption, best/worst consumption, mpg/km pr litre etc.
Once you have put in the size of your tank (litres or gallons) it will also indicate maximum range of bike/car. Handy.
Fuel consumption changes can often be a sign of something wrong, or mal adjusted on the bike/car, so I use it for this reason also.
