The decisive scene
Hamilton: Lap 61 offer and Lap 62 intermediate stop
The extra slick lap exposed Hamilton to worsening conditions; the team’s correct tyre instruction must not be rewritten as a stay-out call. The isolated time and finishing-position costs remain unknown.
Featured decision read: MIXED
01
Ferrari's call
Ferrari called Hamilton for intermediates on Lap 61, but he continued while chasing Lawson, then spun and stopped on Lap 62. The replacement intermediate set was new.
02
Why the answer stays bounded
Hamilton recalled adequate grip and an earlier forecast of similar rain, while saying the call came just before pit lane. Exact radio lead time, potential delay while waiting behind a teammate and an alternative return into traffic are unmeasured.
Decisive evidence
Hamilton's running order around Lap 62.

What the visual shows
HAM: The checkpoints move from P7 at L61 to P9 at L64.
Why it matters for Ferrari
The recorded order changed. These checkpoints alone cannot identify a pass, a position return, a retirement or a timing correction, or isolate the stop's effect.
How to read this evidence
Look atRead the labeled lap checkpoints in time order. Equal positions mean no change was observed; missing laps remain unknown. The timing trace and stop checkpoints can have different coverage.
Where the proof stopsPositions are recorded lap checkpoints, not the exact order at pit entry or the pit-exit line. Hamilton recalled adequate grip and an earlier forecast of similar rain, while saying the call came just before pit lane. Exact radio lead time, potential delay while waiting behind a teammate and an alternative return into traffic are unmeasured.

Lewis Hamilton
Hamilton: Lap 61 offer and Lap 62 intermediate stop
MIXED
Ferrari called Hamilton for intermediates on Lap 61, but he continued while chasing Lawson, then spun and stopped on Lap 62. The replacement intermediate set was new.
Confidence: medium
Hamilton: Lap 38 soft renewal
GOOD
Ferrari renewed Hamilton’s softs on Lap 38 as the expected shower appeared to miss the circuit, with the next set first recorded on Lap 39.
Confidence: medium
Hamilton: Lap 14 early move to softs
GOOD
Hamilton was first to pit for softs at the end of Lap 14, with Sainz also stopping that lap.
Confidence: medium
Hamilton: intermediate start from P20
GOOD
Hamilton started on intermediates on the wet track, matching the rest of the field.
Confidence: medium
Charles Leclerc
Leclerc: Laps 38–60 continuation towards the rain
INCONCLUSIVE
Leclerc continued on his first soft set while Hamilton renewed his tyres and Lawson later stopped. This is the observed continuation of the existing plan, not evidence of a new instruction on Lap 38.
Confidence: medium
Leclerc: Lap 61 return to intermediates
GOOD
Ferrari ended Leclerc’s long soft run on Lap 61 and fitted new intermediates, first recorded on Lap 62.
Confidence: medium
Leclerc: Lap 16 move to softs
GOOD
Ferrari changed Leclerc from intermediates to softs at the end of Lap 16, with the soft set first recorded on Lap 17.
Confidence: medium
Leclerc: intermediate start from P14
GOOD
Leclerc started on intermediates with the rest of the field and subsequently reported difficulty generating temperature and grip.
Confidence: medium
Ferrari · both drivers
Team: Laps 59–63 yellow-flag readiness
INCONCLUSIVE
No separate Ferrari instruction is established for the yellow-flag episode itself. Leclerc’s intermediate stop and Hamilton’s rejected instruction are assessed individually.
Confidence: low
Team: Laps 17–20 yellow-flag readiness
INCONCLUSIVE
No separately sourced Ferrari instruction is established for this yellow-flag phase.
Confidence: low
The option still open
The process change is the takeaway.
Complete the offered Lap 61 change rather than defend temporary running order on slicks. Improve the information accompanying the call.
