When they actually drink it
Those 1953 serves do not arrive evenly: the opening hour is the fastest, about 378 serves, because every guest wants a first drink at once; over hours 2–6 the bar settles into a steady 315 serves an hour. The totals above already carry this curve, so the bar is stocked for the surge, not for the average.
Field note: ice runs on the clock, not the guest list
A rule from the Green Jar crews: a 3-hour event still needs 60% of the ice a 6-hour one does, because chilling bottles costs the same however short the night is. Stretch the same party to 12 hours and the order grows to 190% of the base, almost double. That is why the duration of your event moves the ice number more than the guest count does.
