Will the rain barrel run dry before the next storm, with overflow wasting water?

Water that arrives by random rain and leaves by steady use, with a barrel that overflows when full, is hard to judge by feel, and a bigger barrel helps less than players think. This shows how to compute the chance of running short during a stretch of days.

Why this works

A shortage is an event along the way, not a property of the average. Following the chance of each water level day by day, and setting aside the cases that already ran dry, shows how often a dry stretch really hurts, and how little a bigger barrel can help.

When not to use it

Skip it when players can see and control the supply, such as carrying water by hand or following a clear forecast. Then the shortage is their choice, and an honest display of the stock matters more than the odds.
