A typical track day includes 4–6 sessions. Reviewing them together — not just individually — reveals patterns that single-session analysis misses.

In LapBrain
Your career dashboard shows all uploaded sessions grouped by track, with trends and best times for each.

Upload everything

Upload all your sessions from the day, not just the one where you set your fastest lap. LapBrain's analysis improves with more data:

  • Session 1 — often slower (cold track, cold tires, warming up mentally). This is your baseline.
  • Middle sessions — usually where your fastest laps happen. These show your peak performance.
  • Last session — fatigue effects are visible. If lap times dropped, LapBrain shows which corners degraded.
tip

Upload sessions in order. LapBrain uses session sequence to identify fatigue patterns and track condition changes.

What to look for in a day review

Improvement arc

Did you get faster across the day? Compare your best lap from Session 1 to Session 4. The DeltaDeltaThe time difference between two laps or between a lap and a reference (such as your personal best), measured in seconds gained or lost. shows your learning rate for the day.

Consistency trend

Look at the spread of your lap times within each session. If the spread narrows across the day, you're getting more ConsistencyConsistencyHow repeatable your performance is across laps, measured by the variation in lap times or turn times within a session. — even if your absolute best doesn't change much.

note

Fatigue typically shows up as slower reactions — later braking, lower exit speeds, and wider lines in the last session. If your last session is significantly slower, consider whether fitness or concentration is the limiting factor.

What to do next

  1. Upload all sessions from your day — even the ones that felt bad.
  2. Compare your first and last sessions — look for fatigue patterns.
  3. Check your coaching threads — which focus items improved during the day?
  4. Write a brief note of what worked and what didn't — you'll thank yourself before your next track day.
