That thing is a bit inaccurate tho. Install the ACRLFuel app. It will tell you to the second how much fuel you use based on a couple of laps. Just add fuel until you are at 20 minutes + 1 of your laps.

Your point still stands, however. I mean... how hard is it to do 2 laps off line?

Nice heads up on that app, tks.
