Oh, dude, sorry. You can adjust the vss (or fuel) by the percentage that it is off and get it in like one shot.
if you go exactly 20.00 miles, and the guino says 19.37 miles, then multiply your vsspulsespermile figure by 19.37 then divide it by 20.00, and it should be just about spot on. I guess we need a more refined calibration wiki
