Long-run pace is a driver's representative green-flag stint average from free practice — the closest read on true race pace, because it strips out the qualifying-trim single-lap runs. Gap is the deficit to the fastest long-run in seconds per lap. Clean laps counts stint laps free of traffic and lock-ups. Fuel loads and engine modes still vary between teams in practice, so treat this as a strong signal, not a guarantee. Descriptive practice data only.
