Not a tyre-only effect: car pace, traffic and driving remain in the comparison. No hypothetical Ferrari return position is plotted.

What the visual shows

Leclerc stayed out: hard, 13 laps old → hard, 15 laps old. Russell pitted: hard, 13 laps old → medium, 1 lap old. Verstappen pitted: soft, 16 laps old → hard, 1 lap old. Lawson stayed out: hard, 13 laps old → hard, 15 laps old. Piastri stayed out: hard, 13 laps old → hard, 15 laps old.

Why it matters for Ferrari

A rival's stop tests the alternative Ferrari left open. Compare the tyre and position trade, without treating the rival's finish as Ferrari's guaranteed result.

How to read this evidence

Look atRead the actual tyre age and running order before and after the same race-control period. Pace compares the same valid laps for each pair; positive values mean Ferrari was slower. Shorter windows are available below as a sensitivity check.

Where the proof stopsRussell’s medium did not immediately outperform Leclerc’s older hard, and Verstappen’s comparison changes with the sample period. Exact gaps, signal timing, replacement sets and projected traffic remain missing. Observed pace differences include car pace, traffic, driving and tyre choice. They do not isolate tyre performance, measure time lost by pitting, or simulate where Ferrari would return to the race.

Source boundaryCited decision evidence. Official results anchor the finish; chart values are calculated from checked timing and normalized session evidence.

The option still open

The process change is the takeaway.

Compare the whole remaining hard-to-soft plan with the medium branch, keeping track position only when its expected value exceeds the later cost of pitting.
