Rates between fills
Every litre-per-hour figure is the arithmetic mean over an interval bracketed by two measured fills. No modelling, no smoothing.
Fuel and oil, accounted for.
Consumption trends and maintenance due-dates for the club fleet — computed between measured fills, never guessed past them.

The open segment stays open
Hours flown since the last fill are carried forward at the trailing mean and drawn dashed, on a grey band. They never enter a rate.
Import the club's flight log
Drop in the Vereinsflieger export. Counter readings advance aircraft hours, a Kraftstoff value closes the open segment. Duplicates and tach gaps are flagged before anything is written.
AdvisoryEvery value is derived from recorded fills. The pilot-in-command must verify actual fuel and oil quantities on the aircraft before flight.
