How to use
- Choose whether the race is set in minutes or in laps.
- Enter the race length; for a timed race also enter your expected lap time.
- Enter fuel per lap from practice and a reserve in laps.
- Read the fuel to start with and the rounded-up figure to type into the game or pit menu.
Formula
- Timed race: laps = ⌈race minutes × 60 ÷ lap time in seconds⌉
- Fuel = (laps + reserve laps) × fuel per lap
Example
A 60-minute race at 1:45 a lap, 2.8 per lap and a 1-lap reserve:
- laps: 3600 ÷ 105 = 34.29 → 35;
- race laps alone use 35 × 2.8 = 98;
- with reserve: 36 × 2.8 = 100.8, rounded up 101.
Tips
- Lap times get slower as tyres wear and faster as the fuel load drops; use the average race pace.
- In a timed race, lap times faster than your estimate can mean one more lap than planned — the reserve covers it.
- A full tank weighs more and costs lap time, so do not add much more than you need.
