It really comes from Rental Kart racing where I am on the edge and hitting my lines well, and then someone sliding a lot and not following the racing line easily passes me. Or I look at track records and someone is a whole second faster and I am, and I am trimming tenths. Feedback like “they are just a better driver” is not satisfying. I weigh 218 (going down) so it just may be simply weight, and when I lose it, the mystery will be solved. Still, in one of the chicanes, someone who said they were a kart racer, was quickly turning left just before turning right into the S. This looks like a technique I want to try and see if it works on this particular corner. Maybe I just have a intense curiosity other people don’t.
