We’ve talked about the importance of using reference points to gauge when to make your inputs. The best reference point will of course be some object that is as close to the spot on the track where the input needs to be made. But sometimes there simply is no viable reference point anywhere near your input point. For these situations you can use a different technique, which is to basically to “feel” where the next reference point is.
Take the Left Hander at Lime Rock, for example. It is essentially in the middle of a grassy field, with fresh pavement (read “no markings of any sort on it), AND your braking and turn-in points are usually in the middle of the track, away from any reference points on along the edge of the grass. So what do you do? Probably the best thing is to get into a rhythm and when you feel the same point you know it is time to hit the brakes.
How Does This Work?
The best analogy is to think of a musician. A musician feels the beat and knows exactly when it is time to start and stop. Listen to any jazz musician improvise a solo and you will see this phenomenon in full force. Much as a musician can feel the rhythm of the music and know when to start and stop, a driver can feel their “rhythm” (if you will) through a section of track. Or for those less musically inclined, it’s basically like saying “1 mississippi, 2 mississippi…” and so on.
You Are Still Working Off of a Reference Point
This is the key to this technique: you are working off of a reference point, you just are using a rhythm to gauge how far your next input is after the reference point. Take the Left Hander at Lime Rock again: my reference point is my track out point from Big Bend. Then I feel my way from there to my braking point.
Consistency is KEY
In order for this technique to work YOU ABSOLUTELY HAVE TO BE CONSISTENT!!! ANY change in the previous corner will impact your exit speed, which of course will impact how long you are on the straight and throw off the timing considerably.
That said, you can still use rhythm to pinpoint your next input even if you mess up the previous corner. You just have to compensate for any mistakes you made in the previous section. This all goes back to knowing your line and knowing how and when to compensate for unexpected things along the way. Really its pretty simple: mistakes make you slower, meaning for the same amount of time you will be going slower and will not be as far along the track. So in essence, if you use the same rhythm when you make a mistake, you should be playing things safe for the next corner - at least in theory. (This of course assumes that the car is well balanced through that section and that you are on the correct side of the track and all that jazz). But as always, test this out SLOWLY and work your way up!
