Community Brainstorming for the Next-Generation Mileage Database - Page 4 - GreenHybrid

GreenAndBlue · #31 (**permalink**) 06-20-2005, 11:50 AM

I'd like to see an (optional) label / static field where we could enter our previous 'non-hybrid' vehicle & it's avg mileage (label for the vehicle, field for the mileage. This could then be used to do a " % better" (or worse

than the previous vehicle. Example:

Tank Prev Vehicle mpg % difference
33.1 24.5 35.1%

Helps quantify the improvement available for 'strangers' / 'newbies'

FWIW, since I finally posted to this thread...I agree with the 'one tank purge after a year' as described in the previous post, and as was nixed earlier in a 3rd post. If empirical analysis is desired as to *why* it's better to purge this data than leave it in, I can supply if requested. Thx.

Yup. You better go ahead and provide that analysis

I'm strong opposed to it.

On this page: http://www.greenhybrid.com/compare/lineup/ I think it would be more useful (since there's no graph) to have a range of MPG for each vehicle shown, rather than a single "actual" MPG since it really should be emphasized that it's how you drive that makes a big difference in your FE... ranges are more meaningful when there's no graph (with ranges visually represented) and since this is a real set of data it wouldn't be too hard to calculate.

Hi Schwa:

PLEASE reconsider purging data after a year. This is an essential resource to keep intact and complete. This database enables us to see the learning patterns of ourselves and other new drivers with their hybrids, to see trends (does aging the car make it better or worse), and provides a lot of data to be viewed to test theories that we don't even have yet. There are all kinds of data like driving strategies, effects of summer vs. winter, and the like that will require several years of data to validate. Many thanks for developing and maintaining such a great resource.

I agree. I think maybe the averages should be over many years.

Ability to sort data by month, year, month and year.
Ability to select "all posters" in the database for a given car or "active posters"--those who've posted at least 1 tank/month. I think those who don't keep up really create a bad affect on the usefulness of the whole database.
Allow entry of any number for % highway--just one question "What percentage of this tank was highway driving?"--enter a number. Likewise minutes.

I think some means of sorting by region would be good too. And maybe by temperture--what's the bell-shaped curve look like for driving in 30 degree weather for all of us with a PriusII?

This may be totally silly, but I don't like the green Prius I icon, it's hard to make out any distinctive features of the car, perhaps a lighter color?

I agree that being able to run such age/time-related queries would useful, but rather than deleting valuable data, why not just have the user include the odometer reading, and year (as well as the month as is currently done).

This way you can filter the data, or not, as you need, and (as i would like to do) see if/how the MPG changes with the age/total-milage of the car, not over a given date range (where some cars will be brand new and some will have thousands of miles).

One feature (in three flavors) I'd like to be able to see is the five tank bucket.
Since we base any consistency on a minimum of five tanks, why can't we have:
Best five tanks
Last five tanks
Worst five tanks

I think that this is important for the following reason:

Experience is one of the best factors in driving for economy. Experience is gained by gaining knowledge and applying knowledge. After participating in this forum for nearly three months, my mpg has risen from the mid 40s to 51.1. My current best/last five tanks is closer to 50mpg. And, I believe, it is from applying knowledge gained from this site that was the key contribution. I will take credit for execution only.

What does everyone else think?
