with good inputs.
Every tool includes its formula, source, and assumptions. Use measured values where you have them. Example inputs are here to show you how it works.
Theoretical speed is a gearing calculation. Fuel batch math is a mixing calculation. Neither sets an engine tune.
Setup tools work the same way. You pick the cross weight, the toe, the camber. The tool shows where the car is and what it takes to get there.
