Contour Plot
ProMarching squares over a kernel estimate: rings labelled by share enclosed.

Two populations: a bounce cluster in the first seconds at almost no depth, and a read-through cluster near the end of the article after three minutes. Arrow keys move between contour levels from the outside in, Escape clears the selection. Every level follows as a table.
| Contour | Rings | Density |
|---|---|---|
| 90% | 3 | 360 |
| 75% | 2 | 1,333 |
| 50% | 2 | 2,345 |
| 25% | 1 | 5,859 |
Each ring is labelled with the share of visits inside it, solved from the observations rather than from the estimate's own mass. A ring holding half the smoothed density holds about two thirds of the points, so labelling that one 50% would be a false statement about the data. Smoothing is the other decision: tighten it and the sparse middle breaks into islands, loosen it and the two populations merge into one.
