Predictable spikes that budgets treat as surprises
Event calendars are published well ahead. Despite that, most schemes near a venue set their cleaning budget as though every week is the same and then treat each event as an unexpected cost. The result is a series of variations across the year that nobody planned for and that make the annual figure look erratic when it is reviewed. None of the individual variations is large, and collectively they are what makes the year look unpredictable.
Treating the calendar as an input to the budget changes that entirely. If the committee knows there will be a certain number of high-impact days, it can decide in advance what level of recovery it wants and what it is prepared to fund. That converts a year of small surprises into one decision made once, which is a far easier thing for a committee to approve.
