The Sabbath Experience is a Luu's Foundation gathering. The setup this Saturday was straightforward: pre-issued NFC tickets in the Evoke app, a six-lane gate kit, two roving handhelds, and the live density readout on the organiser dashboard. No miracle, no choreography.
The chart below is the operational chart, just the arrival curve against the planned target. If you want to read more about why the curve matters, the science is in Vol. 01.
Did the time-window plan flatten λ?
Six lanes, two roving scanners
One main entrance, six 1.1 m lanes with belt barriers, one staffer per lane plus a lane captain on the dashboard. Two volunteers walked the queue tail with handhelds.
Roving took 22% of scans
906 attendees were pre-cleared before reaching the gate. The fixed gate stayed at Band C density (1.2 ppl/m²) at peak, well inside the alarm threshold.
Express lane for returning donors
14% of attendees qualified by purchase history. Lane 6 ran 37 scans/min, the highest of the bank, and never queued past two people.
Auto-promote a stand-by lane
~30 latecomers between 15:15 and 15:55 were processed by one staffer who had already finished her shift. The dashboard should auto-promote a stand-by lane when arrivals drop but the event window is still open. Ships v1.4.
