LapBrain has two debrief session types: Practice and Race. It labels each debrief automatically. Race appears when the opening GPS and speed traces clearly show a start and launch near the start/finish line. If your data logger wakes after the bike starts moving, LapBrain can still recognize a clear launch on the main track. If the opening is missing or ambiguous, the session remains Practice. Practice also includes qualifying; LapBrain does not attempt to separate practice from qualifying.
Your day review may also describe one of four run shapes when it compares sessions. These measurements show how the laps unfolded without establishing your goal, mindset, or why the run took that shape.
Steady multi-lap run
Enough comparable laps, held within a tight spread. It describes the lap-time spread, regardless of the absolute pace.
Short run, faster late
A short run whose comparable laps got faster.
Long run, slower late
A longer run whose comparable pace got slower later on. Traffic, conditions, tires, and backing off on purpose all produce the same telemetry, so this measures the pace and nothing about why.
Race-start sequence observed
A run whose opening GPS and speed traces show an on-track start and launch. This can include a recorded grid stop or, for a wake-on-speed data logger, a moving launch that is unambiguously on the main track rather than pit road. When LapBrain sees this opening, the debrief says Race. A start drill can look the same in the recording, so the label describes the opening trace rather than official event registration or the rider's intent.
When a run fits none of them
Plenty of sessions match none of these shapes. Without a clear race start, the debrief says Practice. Corner analysis, lap traces, and coaching work either way.
Where you actually see this
The day review's Pace-shape contrast card compares an earlier steady run with a later run that measured differently. It reports the pace contrast; it does not say why the two runs differed.
