Hey guys,

Just wanted to ask about pit lane times. There is a graphic I found on the forums showing the time spent in the pit lanes of each circuit, but through my own analysing of my races I have found my pit lane times differ quite a lot to this. And while looking at this I found something peculiar; in a lot of races my own pit lane times differ quite sharply.

e.g. Mexico Pit 1: 4.2s + Est Pit Lane time-16.8s TOT:21s
                 Pit 2: 4.1s + EPLT-16.7s                   TOT:20.8s
                 Pit 3: 3.7s + EPLT-15.4s                   TOT:19.1s
                 Pit 4: 3s + EPLT-13.8s                      TOT:16.8s

I have taken the in and out laps into account with a moving average and other calculations too numerous to mention), and even if that calculation is a little off it surely can't account for the 4s+ difference in pit lane times between the first and last pit stop here? Any thoughts?

I have heard that on average tyre changes take 3s to complete (give or take a few tenths), is this correct information too?

I have gone back and looked at a lot of races and noticed the pit lane times decrease the further into a race I am. How can this be if there is a pit lane speed limit? Surely the pit lane time would remain static over the course of a race's duration?

Any help and thoughts would be greatly appreciated.

It should be the slowest time is blank and the fastest time is only 0.5 seconds faster than that. Not 4 seconds in my opinion

Two things coming into mind. One is that pit stops were recently changed to give refueling at practical usable amounts an influence (yes, the tyre change and thus minimal stop time takes 3 seconds) whereas the table times are likely to be based on the former random stop times averaging at ~4.7 seconds, so you'll have to compensate according to your fuel settings.

The second is the question if you took into account that the track is getting faster during the race and thus the in- and out laps will be faster by a few tenths of a second each stop and according to your stopping time you refilled less each stop and thus your outlap was a lot faster due to less weight. Did you already compensate your calculation for those effects?

Hey Frank,

Yes, I calculated for fuel (based on a lot of research and assuming tyre changes are 3s) I found the 'fuel rate' and that matches up to the tyre change + refuelling equalling the pit time in the race csv stats they give us. I have also calculated fuel weight influence, track evo influence and tyre wear influence on lap times (not as confident about that as I could be) but I'm not so unconfident for it to account for a 4s difference in one race. I could understand a few tenths, maybe even a second, to account for errors in out lap/in lap, but for one pit to be 4s quicker is puzzling...
