Has anyone else noticed that octane statistics are calculated incorrectly. When I enter a fill up receipt I enter the octane/fuel grade of that fill up, not the previous one. Despite this, fuelly will apply the MPG data from before that fill-up to that octane. To test this set your most recent fill up to an octane you have never used. You will see that despite not yet having the MPG for that fuel a bar shows up on your octane chart. My only way I can think to resolve this is to edit every entry and shift the octane settings forward.
