how ANALytical do we want to

how ANALytical do we want to get though? if using EPA combined as a measure of hypermileage status, shouldn't we also be recording our % hwy/city proportions in the gaslog? (since the EPA combined figure is weighted at 55/45 city/hwy, if i'm not mistaken - maybe it's the other way around).

last time i figured it out (when i was still using combined data from both fireflies), i was around 70/30 hwy/city. that would make *my* EPA-based hypermileage target 47.5 (calculated), not 46 (as listed).

boo! that would mean i'm now only .09 mpg into hypermileage territory.

i vote we stick with the posted EPA combined as the threshold

I doesn't matter to me. If prompted to enter % trip type I would have to enter 25% highway and 75% city. But my city isn't really city, it is suburban. The EPA combined would the simplest.

I wonder how much the firefly would get on my commute? I would guess 60-65MPG. Next time you are "down under", stop by. We can take a whack at it. :-)

I agree about keeping this one simple. I believe it's impossible for us to know for certain how much of our commutes are highway, and how much are city. I for one won't be driving around with a pencil and paper recording every mile driven. I have a hard enough time keeping track of my gasoline receipts (one of which i can't find btw).

What exactly is the threshold for hypermilage status again? Is it 20% above combined epa?

No, the 20% is Valedictorian status. Here are the details from Wayne Gerdes whom I believe coined the term:

___The following is what the Hybrid pilots should strive too Ö

Insight 5-speed: 65.5 mpg
Insight CVT: 56.5 mpg
Prius II: 55.5 mpg
HCH: 47/48.5 mpg
Prius I: 48.5 mpg
Escape HEV (2WD/4WD): 33.5/31 mpg
AH: 33 mpg
HH (2WD/4WD): 30.5/29 mpg
RXh: 29 mpg

___Non-Hybrid pilotís, please look up your combined EPA estimates from the EPAís Fuel Economy site itself or off your EPA mandated new car window sticker.

Yikes! I just noted SVOboy is on the non-hybrid hypermiler list. And there is a 3cyl Metro at 46.7 MPG but the data is from 2004. Probably no winter tanks in that average.

Image charts

Just spend the morning working on an image function for the MPG graphs.

It's still REALLY basic, but here we go:



While I'm still messing with it, I won't make it part of the garage yet. To make one for yourself, do the following:

Go to your garage entry for your vehicle, and place your mouse over the "edit" button. In the status bar at the bottom of the page you'll see your vehicle ID. You'll see something like "http://www.gassavers.org/node/edit/XXX" where "XXX" is your vehicle number.

Copy that number and put it in this URL:

http://www.gassavers.org/chart.php?vehicle=XXX (where XXX is your vehicle number).

I hope that made sense... My brain is a bit tired now.

Too bad that the women always go for cool looking over consistancy. But since I'm happily married it's OK for me to be boring.
