Is this the record amount of pitstops?
There is nothing there there see. Also your question is unclear. Are you talking about a particular track or across all tracks and at what distance.
The most number of pit stops I have seen in a race is 40(down to a bug where advanced strategy after rain caused someone who wasn’t online to pit after every lap). At 100% the most I have seen in a normal race and win is 5 (Turkey before tyre update). Since update I’ve seen someone try 7 stopping in Turkey, but 5 stops was still winning strategy.
