MPG Accuracy?

[Short Timer_imp]

Thanks MrFerret. I usually use Mileage Keeper but being a wee bit lazy in my old-er age, I figured I'd just let the bike do the work if it was pretty accurate.

BTW, thank you for all of your mod-posts. Very helpful and idea inspiring! I took off my pant-cuff-grabbers today. If I ever get leaned over far enough to hear something scrape it will only be because I've croaked. And by then it ain't gonna matter and I won't hear it anyway.
