For McLaren it says n=63, but pictured on the graphic is 85 pitstops, of which 22 are painted orange. 22/63 is the figure used for the percentage though.
When it comes to pitstops, there are two philosophies:
A. Do them as quick as possible. For that to work, you need your parts to be manifactured a certain way so everything can be done fast.
B. Do them as safe as possible. Thats what Merc are going for, and they have optimzed their processes and parts/Tools to do perfect pitstops that are not as quick.
The thing is, even Ferrari haven't fucked up hardly ever with their faster stops this season, its no longer that faster means mistakes are a regular occurrence.
We saw in 21 that the FIA introduced rule changes around pit stops to make them slower, and for a time this reduced the delta Merc had to the other teams but its grown again, partly as Merc seem to have gotten slower.
They don’t care to try to be faster. They’ve said they’d rather be a tiny bit slower than their competitors rather than just as fast and making mistakes.
Considering that most of the time RB doesn’t make any more mistakes than them it might just be a BS excuse
Interesting! Not doubting you, but if you have a source handy I'd love to see it. It sounds a little BS since again, RBR doesn't often make mistakes and does it faster
