So, I've begun planning my modifications... What's got me stumped is how in the world, around the "Mile High City", I'm going to perform my testing. Between Wind/Weather/Temp, Traffic, hills & FRAKING MOUNTAINS... I know I need "apples" to "apples" tests, so Idealy I don't want to break my tests up over inconsitant periods of time.

so.... I'm Wondering...

Should I plot a simple "Repeatable" path? (instinct tells me yes)
How long should should the drive be? Approximate 1 Gal usage (i.e. Approx 30 miles), 2 Gal (60 miles)?
I'd think that for the best apples-apples comparison, I should attempt to fill up at the same station?

I know in the "scientific" world they have pre-metered fuel, measure distance and how long it takes to go through said amount of fuel... (or how much is remaining and figure out usage divided by distance)... I don't have that kind of luxury
