Keep at it scir, you've got more speed in you. Just focus on keeping all your laps white, first of all it is demoralizing to get multiple red laps and well...they don't count
I'm not worried about the red lap, it's just that when I race against my own ghost, I seem to get slower. I know if I go red though, I've strayed from the line, or hammered on the pedals too much. Both tracks required precise pedal control.
