Why Purple
You measure everything above the waist. Purple measures the rest.
Vision, reaction, cognition, neck strength, heart rate, sleep. Modern driver development measures all of it. Then it stops at the hips — and leaves the two things actually touching the car unmeasured.
The gap sits between the coach and the telemetry.
Both are looking at the same lap from opposite ends. Neither is looking at the driver's feet.
What a coach sees
The result. A braking point two metres late, a corner exit that wouldn't take throttle.
What telemetry sees
The car's response. Pedal trace, speed, yaw. Everything downstream of the driver.
What nobody sees
Whether your foot was late, imprecise, or inconsistent — and by how much.
Everything transfers
A faster foot is faster at every circuit, in every car, in the wet and the dry.
Nothing in Purple is track-specific or car-specific. A skill that only applies at one corner of one circuit is not a skill — it is a memory.
That is the filter every feature has to pass. If the thing being trained does not travel — to a different car, a different series, a circuit you have never seen — it does not go in the product. What you build in Purple you take with you, for the rest of your career.
The pathway
Eye to brain to foot. Three links, each one trainable.
A braking event is a chain. You see the marker. You decide. Your foot moves, finds pressure, holds it, releases it. Every link in that chain has a speed, a precision and a repeatability — and every one responds to deliberate practice. None of them are trained on track, because on track you only ever get the whole chain at once, a handful of times per lap, mixed in with everything else.
Elite reaction
Elite transfer
Elite pressure deviation
Elite repeatability
