Pit-stop rejoin calculator
The question every pit wall asks before the call: if we box now, where do we come out? Enter the gaps to the cars behind and the pit-lane time loss, and see the likely rejoin position, with the near-misses on either side.
Where do you rejoin?
Enter the gaps to the cars behind you, nearest first. Any car closer than the pit-lane loss will have cleared you by the time you rejoin.
Read 4 car(s): 3.5s, 8s, 12.5s, 19s
You rejoin about P10, behind 4 cars.
Cars within the 22s window: 3.5s, 8s, 12.5s, 19s. You fall behind the last of them by ~3s. No car behind is outside the pit-loss window.
Simplified model: assumes the cars behind hold their pace and do not pit on the same lap, and ignores your own out-lap warm-up. Rejoining behind a car is not the same as being passed on merit, and re-passing is a separate problem. Related: undercut & free-stop calculator and how pit windows work.
