How this iGP manager calculator helps

In iGP Manager, race results are often decided by strategy rather than raw pace. This calculator gives you a quick race plan by combining fuel, tyre life, and pit-loss estimates into one suggestion. Instead of guessing whether a one-stop or two-stop is better, you can model your likely race and adjust before lights out.

The core goal is simple: maximize laps per stint without pushing fuel or tyres beyond safe limits. When you do that, you typically reduce unnecessary pit stops and preserve race time.

What the calculator outputs

• Total fuel required for the full race distance, including your margin.
• Fuel-limited laps per stint based on tank size and burn rate.
• Tyre-limited laps per stint from your degradation expectation.
• Recommended max stint length using the stricter of fuel or tyre limits.
• Estimated number of stints and pit stops.
• Stint-by-stint lap plan and fuel load guidance.
• Estimated total race time from lap pace plus pit losses.

Strategy formulas used

1) Fuel requirement

Total Fuel = Race Laps × Fuel Per Lap × (1 + Safety Margin)

2) Fuel-limited stint length

Fuel-Limited Laps = floor(Tank Capacity ÷ (Fuel Per Lap × (1 + Safety Margin)))

3) Final stint length choice

Effective Stint Laps = min(Fuel-Limited Laps, Tyre-Limited Laps)

4) Pit stop estimate

Stints = ceil(Race Laps ÷ Effective Stint Laps), and Pit Stops = Stints − 1

How to get better accuracy

Use these practical inputs for more reliable race plans:

• Base fuel burn from your last practice run in similar weather.
• Use realistic tyre life, not best-case tyre life.
• Increase fuel margin if rain risk or safety car interruptions are likely.
• Use track-specific pit-loss values (some circuits punish stops heavily).

Advanced tips for iGP Manager race planning

Compare two nearby strategies

Run the numbers with tyre life slightly higher and lower. If one setup changes pit stop count, that is often the most important strategy threshold.

Don’t overfuel early stints

Extra fuel weight can cost lap time. If your stint lengths are fixed by tyres, avoid carrying more fuel than needed.

Use margin intelligently

A blanket 10% margin is safe but often slow. Many managers perform better around 3% to 6% in stable race conditions.

Common mistakes this calculator helps prevent

• Planning stints to tyre life while forgetting tank limits.
• Ignoring pit lane time losses when deciding stop count.
• Assuming qualifying pace equals race pace fuel burn.
• Using zero fuel margin and risking late-stint starvation.

Final thoughts

This iGP manager calculator is designed to be a quick planning tool, not an absolute prediction engine. Use it to build a baseline strategy, then adapt in-race for tyre wear, weather, and traffic. Consistently making data-driven strategy calls is one of the fastest ways to become more competitive in iGP Manager.
