I drove the Laguna Seca track with a couple of classes during the last 2 weeks and I fopund some problems/issues during this. My setting for those races where mostly: Race length: 30 minutes AI set: to 100 in the "initialrace" with a class and later, for other races, higher or set to adaptive I noticed, the calculated fuel in the setup isn't right, with most classes you drive 19 to 22 laps in those 30 minute races, if you set the fuel to 22 laps, with most classes the "half fuel" notice from Crewchief comes around 5 minutes left message. So the calculated fuel should be more precise. The other thing is, with some classes the AI will pit during those 30 minute races, even if they should have enough fuel and tires (f.e. the xBow Cup with AI strength set to 100).
