6 fuel-ups in two months now 6 fuel-ups a month?
 

I've fueled up my car 6 times since I joined, on June 3 yet it's telling me 6 fuel ups a month. Last I checked it's July, not June.

A "month" is 30 days, not necessarily a calendar month. Once you have hundreds of fuel-ups in the system the idea of a "month" as a general timespan makes more sense. When you're first starting out and you only have a handful of fuel-ups the number per calendar month seems to make more sense so I understand the confusion.

I have a similar problem... One fuel-up/month since May, but Fuelly says I fill up "3 times per month".

Atebit, been looking that over. To me, it makes sense like this:

You have a total of 3 fill ups. But Fuelly only can give you a MPG for the the last 2 fill ups. And those two fall within 30 something days. So the system thinks you have 3 fill ups a month. However, I will agree that this does appear to be incorrect in your situation.

Atebit, you have three fuel-ups on these dates: 7/13/11, 6/5/11, and 5/16/11. So the first fuel-up was on 5/16 and the last fuel-up was on 7/13. That's a total of 57 days, or if you break that up into 30-day chunks it's 1.9 months. We're dealing with whole months so the system rounds down to 1 month. We could probably be smarter about that. Maybe rounding up to 2 makes sense here.

Once again, this is a situation where you're just starting out so using "month" as a 30-day timeframe doesn't make as much sense as it will when you're 12 months in.

I went ahead and changed this so it will round up. That 57 day difference is now considered "2 months" even though it's not precisely 60 days.
