Fuel log city v. hwy
I would like to have an additional calculated field for % of city driving. Since mpg varies greatly depending upon the use of the vehicle. This allows for comparability between members data based upon environments in three main areas:
1) Ranking (ego, a person who drives 50/50 will never look as good as a person who drives nearly exclusively highway).
2) Identifying if my results are normal (troubleshooting).
3) Reviewing top performers for ideas (potential ideas).

usually hyw mpgs are better. but for me who is allways trying to do the perfect p&g ,
my city mpg are usually better (in my commute). in a random commute my hwy mpgs can be better depending on my chances in the city

I know i dont have a very good write-up
no lean-burn? no good gear ratio? p&g is the answer
MPG=1 TIME=0

Take the fuel logs with a grain of salt, some people only record their records, or certain numbers. Not everyone records all of their tanks. It can be frustrating comparing things, like a one time downhill record against your lifetime, uphill, in Alaska...lol
I completely see your point, as I don't know everyone elses circumstances, like altitude, temperature, drive type, so on, and I would like to know how to compare, but it may just cause more confusion :/

HINT - The ULTIMATE solution is to use a computer to log both MPH and MPG numbers so you can plot your vehicles' actual FE curve...across all your driving speeds.

In summer my Fiesta is better on the Interstate at 60-65 MPH. In winter I can usually do better on my lower speed route. Higher speed aero drag and colder intake temperatures cost me about 10 % on the Winterstate (intentional). The threshold is at 55-60 degrees ambient temp.
The only fuel consumption I do not record in my log is when (very rarely) I loan my truck to my neighbor so he has reliable transportation while his truck gets fixed. He returns the favor when I need a little help with something like unloading a new motorcycle purchase.
regards
Mech

Both CUMMINS and KENWORTH note that comparisons are made in the following order:
1] Vehicle Spec
2] Climate
3] Terrain
4] Vehicle Use (driver skill falls into this)
Just dividing things between city & highway is a subset of the least important factor.
And then other details creep in. I live in the city where, for it's size (and of all cities larger) the ease of moving around is greatest in North America. That's the icing on the cake where climate ("humid desert" accoriding to USGS) and terrain (flat, at 35' above sea level) are the higher considerations.
For comparative purposes I use "South Central US" against very close vehicle spec to come up with a few folks to compare notes with.
And it is possible for "city" to be as high or higher than "highway", remember. The only advantage to "highway" is steady state. I've seen 23-mpg "city" for over 1k miles against tens of thousands "highway" minimum of 24-mpg [average].
I think the best we can do is a general range, and in that, the EPA numbers provide a solid basleine for percentage improbement . . until all the confusiion arrives in a multi-line spreadsheet where how to factor just the BIG diferences is difficult.
But, wish you liuck, nonetheless.

The data acquisition for such a thing would be tedious if it isn't automated.
For me, making a notation for each entry is about the best I'm willing to do.
