WHY SENTINEL.

Recording a ride is not the same as understanding it, and the gap between the two is where Sentinel lives.

The lean angles, the braking spikes, the throttle stabs, the way you carried speed through a corner are all measurable — yet almost nobody connects that raw signal back to the one thing a rider actually wants: to ride better next time.

That is what CHIEF is for: it turns a wall of telemetry into a sentence you can act on, because the goal is meaning, not metrics for their own sake.
