Norris–Verstappen: read the run, then the lap
The fastest practice lap answers one question. A race prediction needs to know what produced it.
Compare run context before ranking lap times.
If a practice chart puts Norris ahead of Verstappen, the first question is whether the laps are comparable. Formula 1’s own testing analysis stresses that different programmes, fuel loads and tyre compounds complicate headline lap times. That principle is useful well beyond a single testing session.

What to watch
Start with the run. Separate preparation laps, clean timed laps, traffic and laps interrupted by a flag. Put tyre compound and known tyre age alongside the trace. When fuel load is unknown, keep it unknown; a precise-looking adjustment can make the comparison less honest. Then look at how the gap behaves. Is one driver faster only at the beginning? Does the difference persist over several comparable laps? Does it vanish when traffic clears? Each pattern suggests a different question for qualifying or the race.

TACTICAL EXPLAINERConceptual illustration — not measured player tracking or a current forecast.
Keep unknown fuel loads visible as unknown.
A slower lap late in a run can have several explanations. Without context, calling it tyre degradation turns an observation into a conclusion too quickly.
What would change the read?
Our forecast would gain confidence from repeated, comparable runs that point the same way. A single peak time earns attention. It still needs an explanation before it earns a prediction.
