Basically, if you're on a straight, on the black line, looking forward at the lane, it rises up in the turns as the banking increases. If you aim to hit the black line all the way around, that's great, but you're still likely to flick up in the turns. That robs you of momentum (even if you get it back) and rhythm and control.......................

At my local track the difference in height of the black line is 8.75cm or 17.5cm per lap (equates to 2.8m for a 4K race).
