The lap passes too fast to process in the moment. TripRank records the session — speed trace over the circuit, G-force through every corner, straight-line splits — so the review afterward shows the lap you actually drove, not the one you remember.

Session records
Every lap traced: where you lifted, where you braked, where the car had more to give.
-
Corner-by-corner G
Load through each corner, plotted — smooth arcs and ragged spikes are visibly different.
-
Progress across days
Sessions accumulate. Compare the same circuit across visits and watch the trace clean up.
Before your first track day
Most first-track-day problems are mechanical and avoidable — brake fluid, tire pressures, loose items. The journal has the checklist that matters, and the reasoning for why the data review afterward is where a first day’s learning actually lands.
A session workflow that stays out of the way
Start the trip in the paddock before the out-lap, put the phone in its mount, and forget it exists until the session ends. Between sessions, the review is waiting: the trace of every lap, G through every corner, and the specific places where the data disagrees with your memory. Across a full day — and across return visits to the same circuit — the traces show whether the driving is actually cleaning up.
Track-day notes
- Mount solidly. Track loads shake loose mounts into noise generators. A rigid cradle is part of the instrumentation.
- Heat and battery. Direct sun plus GPS plus a long day is the hard case — a vent mount and a top-up between sessions handles it.
- Prep beats pace. Most first-day problems are mechanical. The checklist that matters is in the journal.
