i think fuelly needs to learn to count
 

have a look at the graph on Hyundai Ioniq MPG - Actual MPG from 132 Hyundai Ioniq owners

then look at the numbers for the X axis, they are not in order :O

minor bug me thinks :)

Oh yea, I see, starts going up, then counts down one now and again lol.

I don't see any problem. Where the real problem lies is in the engine choices like the V8 chosen by one Toyota RAV4 owner or the V4 (1) or L2 (2) or H2 Diesel (1) or unidentified GAS (16) DIESEL (8) ELECTRIC (1). Those 29 and possibly a few more should not be included in the averages unless/until they have proper engine identification so they aren't messing up the averages and data for everyone else.
