My excellent crew chief, Jeff Denton, built a spreadsheet where you put in the stage miles, transit miles, and number of gallons you put in at each service. Then the spreadsheet does a least squares regression on the data to arrive at both your stage *and* transit MPG, without knowing either to start with.

Of course, it's better to measure your transit MPG in the traditional way, you'll have fewer variables that way. But I can understand not wanting to drive off $50 in race gas just to find out what your transit MPG is.


Cheers,
Anders

Three votes so far for "both", and zero for all other choices. For the moment, people seem pretty conscientious about this.

Oh, I didn't think of that. I added it to the poll.

Why do you want to know this?

In the good ol' days we stopped at these places that had tall things with numbers on them and a hose. We would put the hose in the car, pull the handle, wait a bit, put the hose back, pay the dude.

After using those tall things with the hose, we could often walk into an attached building that had females serving food.

Ah... the good ol' days when life made sense.

I'm not asking why someone would want to know what their mileage is.

I am asking why Anders wants to know how many people check their mileage.

Knowledge is power, eh? Okay... here we go....

Has anyone calculated the differences in performance (acceleration, stage times, etc) between carrying a 100 lb co-driver and a 300 lb co-driver?

Jens,

"Knowledge Is Good" is an Animal House reference. :D

But, I agree that rally guys shouldn't get too picky about MPG. Too many variables. Even progressives should adopt a little conservatism in this circumstance.

"Animal House" (one of my favorites) is a good metaphor for the rally community. :)

Name the real rallyist counterparts of the following:

Bluto
D-Day
Otter
Flounder
Neidermeyer
Dean Wormer
Mrs. Wormer

HAA!!!

Now that's a pretty good question. Jens, I'm afraid you'll have to file it under "questions one would ask during the long tow home", as in


Driver, towing home: "Hey (insert codriver name), how many people do you think bother figure what kind of mileage their rally car gets?"

Codriver, sleepily: "If you could stop swerving and taking up both lanes, I wouldn't feel so queasey."

Refuse to answer - Ever bother to figure out the MPG your rally car gets?

I refuse to vote because the response "Not only NO but F--- NO" ain't there.

Whatever mileage the Bug gets I'd sacrifice most if not all of it for some grunt. If the Omni GLH turbo and/or Peugeot V6 both get s----y mileage but make enough grunt to accelerate up a steep hill, that's fine by me.

shhhhh...Jens don't open that can o'worms or all us
big blokes will be out of rides, obviously 100 lbs difference is major, but will said 100lb jockey/navvie be as skilled (well, probably, damn time to start running 5miles a day.)

RE: duplicate: delete please

We do calculations and fill up to exactly what's needed to the liter, plus about a 5 liter buffer. We know the averages for stage and transit seperately. Otis generally comes back with 6 to 9 liters left, so the calculations work pretty well.

If you don't measure it, how do you know if you are bringing enough fuel in the service vehicle?

Mhmm: everything in moderation, even moderation!
