Yah, I think I had a problem hitting turn 15 correctly. I would just drift into the pit lane every time. I was all over whoever happened to be in front of me out of turn 7 onto the back straight, but I'd lose most people coming out of the toilet bowl. I blame my tires.
On the 3rd run, my instructor, Skip, did a real good job of pointing exactly where he wanted me and I was noticibly faster...especially in the straights since I was exiting turns faster.
