Channels without a public source

These are on your spec but no public feed carries them. They are shown hatched rather than filled with invented numbers. Estimates for a few are on the Analytics view.

There is no public dataset of F1 circuit outlines. This app reconstructs each one from where the cars actually were — the fastest lap of the race, and that driver's GPS for its duration. If the browser can't reach the API (sandboxed preview, offline, corporate proxy), fetch the file yourself and drop it below. Same data, one extra step.
Step 1 — open these, save the results
Find your round's session_key in the first, put it in the second, then save that page.

Track evolution

derived
Session-best lap time against wall clock. A falling line is rubber going down. Flat means the track has stopped improving — the cue to send the car out.

Analytics

Everything here is computed, not measured

Predictions

Model outputs with the inputs they rest on

These are heuristic baselines, not trained models — a Monte Carlo over pace, degradation and safety-car hazard. Swap Predict.* for real inference when you have a labelled history. Every number below shows the features behind it.
