One great thing in rFactor 2 is the ability to run up to 4 races. The problem is that if the race 1,2 and 3 are 10 laps, I can not make the race 4 has a length of 20 laps. Actually could with the command / racelenght, but the idea would leave automated. Would be good in the rFDedicated configuration screen, you can select the length of each race individually. Sorry for my English, I helped with the Google translator.
It's in the PLR file (up to 4 practice/qualifying/race) sessions: Run Practice1="1" Run Practice2="0" Run Practice3="0" Run Practice4="0" GPRIX Num Qual Sessions="0" // range: 0-4 GPRIX Num Race Sessions="1" // range: 1-4 But I think it is the same for each of the sessions - you can't set the length of the sessions individually.
Administrating a multiple race event is a real pita at the moment. Especially if you want to change weather, edit the starting grid, the last .rrbin for a 2nd race, yet start the evening with a green track and want to participate in the races yourself. So here's my +1 since after my suggestion this hasn't been implemented yet.
