I may be wrong and probably am but doesn't your fuel gage constantly recalibrate your mileage as you ride? If you drive around town and are a little hard you may get say 100 miles out of a tank. Now when you fill up doesn't the gage state what your last mileage was so it would register lower and maybe show 120 miles (based on the previous tank of hard riding). I noticed on long hauls on the freeway when I fill up my mileage on the fresh tank of gas has gone up to 165miles on the last tank of say 45 miles to the gallon. Now that 165 will drop fast if you start the hard riding again and may show 150 miles even though you have only gone 10 miles. It constantly recalibrates due to the type of riding. Am I stating the obvious or just incredibly wrong?
