a completed wait — darker is longer the wait still running — a lower bound, not a finished gap

What this cannot tell you

Nothing here predicts the next draw. A number’s history is a record of a fair machine’s past, and the machine keeps none of it: 21 is drawn with probability 6/43 tonight whatever it did last week.
