at times such stats / charts explain nothing more that just simple digits.
it is telling me ferrari are so.good in pitstopts but for eg. in imola as i remember in perez had a 2.27s stop , next lap Leclerc had 3.7s stop. leclerc still came out a second ahead but due to cold tyres he couldn't defend against perez. these are fine margines where RB are spot on. im pretty much sure had leclerc had a similar stop he would have been at lest 2 seconds ahead which would have given him plenty of time to warm up the tyres. May be he would have kept the place and that costly spin would have been avaoide.
Fect is ferrari or even mercs are no match to RB in pits and strategy . revisit last season and calculate how many points Max won due to RB's excellent performance.
