Three fixes ranked by the time they're worth. S6 mid-corner is the big one: 0.11s.

The verdict sits above the graphs.

Every other tool opens on a wall of channels and lets you go hunting. PURPL opens on what happened, what to change, and what it's worth. The traces are still there, one scroll down, when you want them.

THE READ

You're 0.413s off your own potential this session. The biggest single chunk is S6 mid-corner. Find 0.11s there and the rest follows.

Ask where the time went. Watch it happen.

The Race Engineer doesn't just answer: it drives the app. Ask about a corner and the replay jumps there, on the line you actually took, at the speed you actually carried.

S6 mid-corner, and it's your biggest single chunk: 0.11s against your own best pass through it. Need more minimum speed. Want to watch it?

YOUR DRIVING FOCUS

Your speed is there. Your braking point still moves ±1.6 m between laps; repeatability is the next step, and it's the most coachable thing on this list.

A season is not one session.

One bad Sunday means nothing and one good one means less. PURPL scores the driver on rolling 30-session windows, so what you see is growth: not weather, not a fresh set of tyres.

Ten relative metrics, all normalised against that session's own ceiling, so changing track doesn't break your trend.The weakest metric becomes the month's focus, in a sentence a 14-year-old will actually act on.

The same read, in your glove.

SEAT TIME IS THE OTHER HALF

The training log is right next to the lap times, because the honest answer to "why am I not improving" is often 90 minutes a month.

One session. Three different questions.

DRIVER"What do I change this heat?"

Leads with the three fixes and the corner map. Never asks him to interpret a graph under pressure.

S6 mid-corner → 0.11s
PARENT"Is this money doing anything?"

Leads with the month: momentum, new PBs, consistency. Growth over a season, not a lap table.

Nico is −0.41s this month, +4 score
COACH"Who needs me on Saturday?"

Leads with the roster: whose DNA slipped, whose braking is drifting, who is ready for the next step.
