Your Pace percentilePace percentileHow your best lap ranks among riders in the same bike class at that track; 75 means faster than about 75% of that group. tells you how your lap times compare to other riders on the same bike class at that track.
How it's calculated
LapBrain compares your best lap time against the distribution of best laps from other riders on the same bike class at that track. A 75th percentile means you're faster than 75% of those riders.
What it means
| Percentile | Interpretation |
|---|---|
| 90th+ | Front 10% of recorded riders in the group |
| 70th–89th | Faster than most recorded riders in the group |
| 50th–69th | Upper half of the recorded group |
| 30th–49th | Lower half of the recorded group |
| Below 30th | Back 30% of recorded riders in the group |
A percentile is a snapshot of one group on one track. Who else rode there, the weather, tires and setup all move it.
When you won't see a percentile
A percentile only appears once enough riders on your bike class have ridden that track and opted into anonymous comparison. Drawn from a handful of laps it would move by tens of points every time one more rider uploaded, so until the group is big enough there is no number. The "Riders around your pace" panel on your debrief tells you when that is the case.
Important context
Your percentile at different tracks may vary significantly: a rider who's 80th percentile at their home track might be 60th at an unfamiliar one. That's normal.
The trend shows how your position within that group changed across sessions at the same track. Read it beside your exact lap times because the rider group can change too.
Don't treat percentile as a target by itself. Use it as context alongside your own lap history, conditions, and Focus recommendationFocus recommendationThe corner or riding pattern LapBrain puts forward for you to review next. s.
What to do next
- Check your percentile trend: is it climbing, flat, or dropping across sessions at the same track?
- Look at corner-level data: lap time combines the full lap. Turn Phases helps locate where a pairwise time gap changed.
- Choose your next focus from the debrief: use the percentile as peer context, not as a technique grade.
