In the early days, some folks actually were playing with the fueling tables (programming). Matt (from Spartan) may have been one of them. It is pretty much the same principle as the lie-o-meter. IIRC, they (whoever they are) came up w/ close to the 0.8 gph number. We all know that the lie-o-meter can be off by 10 or 20% (or more) though.
I will try to find the old posts.
