Consumption (from 3–4 practice laps)
Pit Stop
Base stop assumes a full refuel (~90s). Tyre time is added on top only on stops where the compound calls for a change.
Fuel Saving
Fuel Saving assumes you can stretch every stint by 1 extra lap beyond the natural fuel/VE max, at the same pace — no lap-time penalty assumed.
