I found many servers with ranking systems, there are many leagues but I dont remember pick-up servers multilplied for divisions ie. with 2s range of laptimes.

I can cope with 105% of WR mostly that is used for some servers as a need and from my experience 2 seconds is the difference that makes the sprint race. So if there were couple of servers for the same combo with thresholds (WR+2s, WR+4s, WR++) much more racers could enjoy close races.

Its not only about hotlaps, you can have fun with a much slower driver than you...

with 2s of laptime difference...? 2 or 3 laps max.

You were talking about sprint racing dont you ?

yup, 5 to 10 laps

btw. just an idea for meeting room when looking for pickup race:

at connecting everyone can upload profile of desired combos. And then can see how many ppl are connected wishing to race at this combo with similar PB with possibility to send a message: lets go, find a server and race there
