Frequently Asked Questions

Getting started

What data loggers does LapBrain support?

LapBrain currently supports AiM (XRK/XRZ), MoTeC (LD/LDX), and RaceChrono (VBO/RCZ) formats. See the Data Logger Setup section for step-by-step instructions for each: AiM, MoTeC, RaceChrono.

How long does processing take?

Most sessions process in 30–60 seconds. Complex sessions with many laps may take slightly longer. See Your First Session for a walkthrough of the processing stages.

Do I need GPS data?

Yes. LapBrain requires GPS latitude and longitude channels to generate track maps and corner analysis. Without GPS, the session will be decoded but Turn phasesTurn phasesThe five stages of every corner: Entry, Decel, Maintenance, Accel, and Exit. Each phase has distinct techniques and metrics. and coaching won't be generated. Check your logger's setup guide to verify GPS is enabled.

Can I use my phone as a data logger?

Yes — RaceChrono turns your phone into a data logger using its GPS. Results are best with an external Bluetooth GPS receiver, but phone GPS works for coaching recommendations.

Analysis

What is a "focus recommendation"?

Your Focus recommendationFocus recommendationA coaching area ranked by potential time gain and your current skill level. LapBrain shows multiple focus recommendations so you can choose how many to work on. s are coaching suggestions ranked by time-gain potential and actionability. The top item is the highest-impact change, but LapBrain shows multiple focus areas so you can choose how many to work on. See Understanding Coaching for how to act on them, and Acting on Coaching for translating recommendations into on-track practice.

How does pace percentile work?

Pace percentilePace percentileA 0-100 score showing how a lap or turn compares to your own range of performance, where 100 is your best and 0 is your worst. compares your best lap time to other riders at the same track. See Pace Percentile for a full explanation including what the numbers mean and — more importantly — why the trend matters more than the number.

What are turn phases?

LapBrain breaks every corner into five Turn phasesTurn phasesThe five stages of every corner: Entry, Decel, Maintenance, Accel, and Exit. Each phase has distinct techniques and metrics. : Entry, Decel, Maintenance, Accel, and Exit. Each phase has distinct techniques and distinct metrics. See Turn Phases for a detailed explanation of what each phase means and how to read the data.

What are coaching threads?

A Coaching threadCoaching threadA specific, actionable area of improvement identified by LapBrain's analysis, such as 'trail braking in T5' or 'consistency through the esses.' tracks a specific recommendation across multiple sessions at the same track. When LapBrain tells you to improve something, it watches for that change in your next session. See Coaching Threads for how threads work and why they matter for long-term improvement.

Why do my corner numbers differ from the track's official numbering?

LapBrain detects corners from GPS data and numbers them sequentially. This may not match a track's official corner names (which sometimes skip numbers or use names). The track map always shows which physical corner each number refers to.

Using LapBrain effectively

How do I get the most value from LapBrain?

Follow the briefing-session-debrief loop: review your Focus recommendationFocus recommendationA coaching area ranked by potential time gain and your current skill level. LapBrain shows multiple focus recommendations so you can choose how many to work on. before riding, focus on one thing during your session, and upload immediately after. See Acting on Coaching for the full workflow, and Track Preparation for building a pre-session plan.

How many sessions do I need to see improvement?

Most riders see measurable improvement within 3 sessions at the same track when following coaching recommendations. Cross-session comparison unlocks after 2 sessions, and trend analysis improves with each additional session. See Comparing Sessions.

Should I upload every session, even bad ones?

Yes. LapBrain's analysis improves with more data, and "bad" sessions often reveal useful patterns — fatigue, inconsistency, or specific corners that degrade under pressure. See Day Review for how to get value from multi-session analysis.

Data & privacy

Who can see my data?

Only you. Your telemetry, lap times, and analysis are private to your account. Aggregate statistics (like Pace percentilePace percentileA 0-100 score showing how a lap or turn compares to your own range of performance, where 100 is your best and 0 is your worst. ) use anonymized data and never reveal individual riders.

Can I delete my data?

Yes. You can delete individual sessions or your entire account from the Settings menu. Deletion is permanent.

Troubleshooting

My session shows "Track not found"

This means LapBrain couldn't match your GPS coordinates to a known track. This can happen if GPS accuracy was poor or if you're at a track that hasn't been ridden by any LapBrain user before. The track will be resolved automatically once better GPS data is available.

My lap times don't match my logger's display

LapBrain may re-cut laps if the start/finish position in your data doesn't match the track's actual start/finish line. This ensures consistent comparison across sessions and riders. The total session time will be the same; individual lap boundaries may shift slightly.
