On road testing is really problematic.There are just so many variables to deal with and is reason for so many wind tunnels today.
My last trip had a spread of 28-47 mpg.
Where I was 'certain' I would set a new record I didn't.Where I had no expectations of seeing record mileage I realized my highest ever.
If we see any 'trends' emerge from our baseline data I figure we're doing good.
Appreciate the diligence and diciplined record-keeping.Damned nice MPGs!
