H08 — London pilot
Intent
Dense repeated observations > shallow network-wide coverage.
Priority (working)
Central · Jubilee · Victoria · Northern — noisy + quieter contrast sections.
Sample mix
| Dimension | Vary |
|---|---|
| Devices | Several iPhone models |
| Time | Peak + off-peak |
| Carriage | Front / mid / rear; seat vs stand |
| Load | Crowded vs quiet |
| Reference | Some runs beside Class 1 / known SLM |
Success (qualitative)
- Alignment correction usable without training
- Tiers/flags visible in analysis
- Privacy flow works offline → later upload
- No false precision on the first map cut
