A few of us used a website that we would log our miles in and it would calculate how many days we owned it and how many miles per day we averaged. It recently shut down, so I asked my daughter to make me one. It is not password protected so if you use it try not to screw with others miles. But you log in the date you bought it and how many miles were on it. It calculates your average miles per day, month and year. here is the link. https://docs.google.com/spreadsheets...it?usp=sharing
If you see annoying diagonal stripes, uncheck "View"--> "Protected ranges" from the menu at top
