If you want absolute confidence that you will ace each corner every time, you need a detailed plan of how you will take the corner.....otherwise how will you know you got it right?
By a detailed plan I mean you can use all of the following.
- Braking point
- Turn in point
- Brake release point
- Throttle on point
- Apex point
- Maximum throttle reached point
- Exit point
- Revs at exit
You should be able to mark all these points on a corner diagram, and if you want to be precise you need as many physical on track marks included, like patches on the track or particular parts of kerbs.
That corner diagram represents your plan of how you take that corner, and if you want to alter that plan the place to do it is NOT on the track whilst you are driving.
If you feel that you can go faster round a corner, then you can make changes on your corner diagram in the pits before you go out and carefully consider how you will make it work. Then spend the next track session doing your best to drive the corner as close to the plan as possible.
After the session you can then sit down and consider the results of your experiment and create another plan if needed.
This is a methodical approach that is far superior to what everyone else does, which is to drive round all day randomly changing their driving hoping to find the sweet spot - if they are lucky they will hit a sweet spot but likely forget it! You however will have it all written down and burnt into your mind.
My drivers use diagrams with colours and a few clever tricks that they can recall in a flash before they approach each corner, they then feel absolutely confident of how they need to take the corner. Once they have driven the corner a few times they start hitting all their points on autopilot. That's when they start to experience flow and a feeling of being in the zone, because they are able to continually measure how close to perfect they take each bend (being in flow depends on getting high quality feedback continuously).
