When no length passes, the default 30 m is kept. The leave-one-day-out Poisson deviance (and its 1-SE rule), the obs/h reliability and the hotspot Jaccard are reported as diagnostics only. 30 m is a good default for 20 s polling at urban speeds; go shorter only with dense GTFS-RT fixes and many days. `--sensitivity` [excerpt truncated]
