Every lap, sector, and pit stop from the Monza timing feed — translated into plain English. Start with who was fast; drill into the telemetry whenever you want it.
1:31.982 — the fastest lap of final practice, 0.122s clear of Norris's McLaren.OBSERVEDDERIVED
The model credits roughly 40% of Ferrari's edge to Leclerc and 60% to the car.MODEL

Gaps are each driver's best lap minus Leclerc's 1:31.982 — simple arithmetic, no model involved.
The model's calibrated chances per driver. A probability is not a promise.
Leclerc's 1:31.982 (lap 11), measured against the fastest track third anyone set all session. Bars show time gained or lost vs. the best — centered on zero.
Session bests: S1 28.310 (Norris) · S2 33.912 (Leclerc) · S3 29.694 (Verstappen). Leclerc's lap adds up: 28.351 + 33.912 + 29.719 = 1:31.982.
344 km/h at the finish line — Monza is the fastest circuit on the calendar, and it shows.
Softer tyres are faster but die younger. This is what the rubber actually did across the stints — and what the one pit stop cost.
12 comparable laps · fuel-corrected · ±0.012 s/lap. After 12 laps the soft tyre has cost roughly a full second — that's a pit stop earned.
Chronology: Stint 1 · Soft · laps 10–13 → pit stop → Stint 2 · Medium · laps 14–17.
14:32:38.884 − 14:32:11.184 = 27.700s elapsed. Track position: P2 → P2 — nothing lost. Soft → medium.
Was it Leclerc or the Ferrari? The model splits every lap into a driver effect and a car effect, relative to a grid-adjusted expected lap.

In lap = the slow lap into the pits · Out lap = the slow lap back out on fresh tyres — that's why lap 14 has no sector times. Lap and Time columns stay pinned while telemetry scrolls.
Hot asphalt, warm air, no rain — ideal conditions. Context, not the main event.
Every value on this page is rendered from one canonical session dataset — no number is typed twice. Before publishing, automated checks verify: session best equals the fastest valid lap, leaderboard gaps equal best-minus-P1, sector sums match lap times, and pit elapsed matches the timestamps. A value labeled Observed was measured; Derived was calculated; Model was estimated — and every model value carries its version.
