Stats and Standings: Beginning July 2, 2007

Hey FETC Challengers...

Here's the new spot to report weekly accomplishments or tank updates. As soon as I get off my lazy bum, Cycle 3 updates will be posted. Good luck!

I filled up last night. I travelled 388.0 miles and used 4.78 gallons for 81.17 mpg. I'm going to Hybrid Fest 2007 and I'm leaving about 6:30 pm Friday and coming home Sunday. This highway trip will pull the numbers down a bit but I'm hoping for 75 mpg on the tank by the time I get back.

filled this morning. 606.3 miles on 8.713 gallons = 69.59 mpg. I fell below 70 , I blame the 200 miles of highway driving I don't normally do that was on this tank (55-60 mph min with no EOC ops + some wot to 60 mph merging with semis). Yeah, excuses excuses.

Commish, does this mean we don't need to report to our team captians anymore, just post it here? Here's my latest:

Porthos, Team OPEC Busters. 07/23/2007, 445.116m on 13.11g for 33.93 US mpg.

Not as good as last week, but still better than my pre-mod PB. Mods this tank: 40psi in tires, partial grill block, shaved passenger mirror.

That's right -- with several teams, updates are based on actual GasLog data (easier and more accurate). Which reminds me, current stats/standings should be updated in the next day or so...

Keep up those great tanks...

Commish,

Since you're getting the data from the Gaslogs, I have to ask -
Per each car, are all miles equally weighted? That is, are you totalling up all the miles and all the gallons then dividing? That method weights all miles and gallons equally for that car.

Or the alternative would be to grab the mpg values directly off the gaslogs, and average them. That method weights each tank equally - so a short tank of only 4-6 gallons and maybe 100-200 miles would have as much "weight" (significance) as a long tank of 10-20 gallons and many more miles for that same car. If the short tank was unusually high or low mpg for whatever reason, then the short tank skews the results.

I had to ask....

[rh77]

Oddly, no -- it doesn't. The tanks are averaged regardless of cumulative distance/consumption.

Manual calcs of the baseline use the same technique.

As I think about it, this is an excellent point. With the data extraction that I receive, it would be simple enough to implement the cumulative procedure.

If everyone is cool with the new plan, it will take another week to get an approximate stats/standings published.

Standby for a poll...

I agree. The only way to do it and be objective is to do it per total miles...otherwise some joker with really good MPG could fill up 3 gallons at a time to increase his/her team's stats.

I myself am considering 1) "calilbrating" the lower end of my gas gauge (i.e. when needle was at 1/8 it took 9 gallons to fill), then 2) making a drop down in fill up volume by waiting until the needle hits 1/8 and only put in 4-5 gallons of gas (the same amt every time). This will lower my vehicle's average weight by 20 lbs. or so and potentially increase FE.
