Just tested some Toscana Tarmac settings.
4 sections. I think leaving it here is fine. Maybe 3 if we want more laps.
Complexity 2 - very high speed, a couple of slower corners but I can see a real draft fest. Easy to get the hang of.
Complexity 5 - good compromise for high and low speed corners. A little harder to memorize.
Complexity 7 - quite a few slower corners, some higher speed sections but not as many high speed corners. A little harder to memorize yet.
Complexity 10 - barely got into 5th gear, lot's of low speed corners, barely any high speed. Seemed frustrating and probably hard to get the hang of in 15 minutes of qualifying. Really hard to memorize.
Had the most fun with complexity 5 or 7. Will play a bit more
