Edit: 4/5 Stars, because its completely random which AI driver takes which endpositions in races. Just changing the ai level between 80 and 100 doesnt create a realistic Season. Content Manager still seems to be the only way to config the AI drivers talents and aggressions. If this would be possible in this mod, i´d give 6 of 5 stars.
Unfortunally ACCG is no longer supported do lack of time, about change wheater between qualify and race, i don't know if now it work (at the time i wrote ACCG it doesn't work) but you can try to edit the event.ini file and made some test, same for the maximum grid.
