How to use entry, minimum, and exit speed
Every corner has three easy speed numbers: what you carried in, how slow you got, and what you carried out. The mistake is trying to maximize one of them. A higher minimum speed means nothing if it ruins the exit.

The main idea
A slightly lower minimum can be faster if it creates better rotation and earlier clean acceleration. A higher minimum is useful only when the line remains controlled and the gain survives the exit.
What to look at
- Where the slowdown begins
- The shape and location of minimum speed
- Speed when acceleration becomes sustained
- Top speed or delta on the following straight
Try this
- Overlay two clean laps
- Mark consistent corner boundaries
- Compare the full speed curve, not isolated values
- Check whether a higher minimum changes the path or exit
- Follow the delta until the next braking zone
Keep in mind
GPS speed and corner boundaries have resolution limits. Avoid treating a tiny difference at a single sample as a driving conclusion.
FAQ
Is higher minimum speed always faster?
No. It can compromise line, rotation, or exit and lose more time afterward.
Where should exit speed be measured?
Use a repeatable point after the apex and also check the following straight, where a genuine exit advantage continues to accumulate.
