What is an optimal lap?
An optimal lap combines the quickest valid segments from different laps in one session or comparison set. It estimates what the driver might achieve by joining those best segments together, but it is not a lap that actually happened and can be unrealistic when segment boundaries, traffic, changing grip, or incompatible driving choices distort the calculation.

How it is calculated
The analysis divides a lap into sectors or smaller segments, finds the quickest valid time for each segment, and adds those times together. Some products call the result theoretical, ultimate, or optimal.
What it tells you
The gap between best actual and optimal suggests how much recorded performance was left unassembled. A small gap can indicate consistency; a larger gap can identify sections worth reviewing.
Why it can mislead
- A partial or impossible lap may win one segment
- The fastest entry to one segment may compromise the next
- Grip, traffic, tires, or weather may change during the session
- Different start lines or layouts can produce incompatible segments
Use it as a prompt
Treat optimal time as a direction for investigation. Open the contributing laps, confirm those segments are valid, and identify one combination that is physically repeatable.
FAQ
Is an optimal lap the same as my fastest lap?
No. The fastest lap actually occurred. The optimal lap is assembled from the fastest recorded segments across multiple laps.
Can optimal time be impossible?
Yes. Segment interactions and invalid source laps can produce a combination that is not realistically repeatable.
How should I use the optimal gap?
Use it to find promising sections, then inspect and validate the source laps before setting a target.
