Calculations and limits
Section titled “Calculations and limits”Lap consumption = starting liters − ending liters. Uses the last valid lap, mean of up to five and observed maximum; excludes partial laps, refueling, pits and caution. For fuel F, consumption C, remaining distance R and margin M: range=F/C; add=max(0,(R+M)×C−F). Add is extra fuel, not a target tank level. Timed-race finish is estimated; missing consumption/finish never becomes zero. 1 US gal = 3.785411784 L; SDK flow is kg/h, not L/h.
