I just finished level two and three yesterday. I think the last drill on level 3 will help you for sure to get out of that lost feeling when you charge in and get slowed down. Pace comes with practice not with trying to chase down people you just cant catch. Also taking advantage of areas on the track where you are faster than others or simply sacrificing time entering a corner in order to get more drive and ultimately more speed coming out.
I was very concerned about my pace to. After level two I drastically improved my pace. Then with the addition of the tools you pick up in level 3, I found myself getting around the track considerably faster than I ever thought I could.
I would be interested in knowing your impression of your pace once you've finished level 3.
