You know how lot's of people say "Slow is Fast", there is a logical reason to that. I am faster coasting through a certain section of my track than trying to "blast" through it. When I am concentrating on smooth lines instead of loads of throttle, brake, run wide, throttle, brake and so forth, I end up carrying more speed through the ENTIRE lap instead of just being quick through one section then shooting wide and loosing all that time advantage with a mistake. Find a rhythm through the track and once it's second nature start pushing it to see where you can make up time and where it's better to just coast through.
