What actually deteriorates during a break
Not evenly across the building. Amenities decline fastest, particularly where they are still in use, because consumables run out and nothing is being reset. Kitchens and staff rooms follow, since food waste left over several days produces odour and attracts pests. Waste points overflow. Entries and high-traffic floors accumulate soil that is then walked further into the building each day. Offices and low-traffic areas change very little.
That unevenness is the basis of the recovery plan. Spreading the first shift evenly across the building treats a lightly used office the same as an amenity block that has had four days of trade, which produces a shift that finishes on time and leaves the worst areas only partly recovered. Weighting the effort deliberately is what makes the first night effective. Deliberate weighting is the difference between recovery and a shift that merely finished on time.
