I’m going to copy and paste and save this to make life easier for me
Last year best way and probably still the best way to calculate your ai is. In career or my team mode if your teammate has a pace rating off 85+. During practice go to race director and compare your time with his when his lap times when on mediums. For every second your faster/slower increase/decrease ai by 10. If your teammate has a lower rating. Go to the closest team in the rankings that has a Driver with 85+ and compare with him Won’t be perfect but will put you in the ball park. Then just fine tune.
Cant be sure this will work as well as last year because off the ai being out off whack. But like I’ve said many a time whenever lando or button were my teammate I’d qualify within half a second off him. And we would finish a 50% race within a few seconds off eachother.
