Seven-day kit: test the laundry assumption

Illustrative case: one traveler, seven wear days, laundry every three days and one spare set. A laundry interval is useful only if clean, dry clothes are available before the next rotation begins.

WORKED EXAMPLE
Reliable laundry | min(7, 3 + 1) = 4 sets | Start with four tops, underwear and sock sets.
Laundry slips to day five | min(7, 5 + 1) = 6 sets | Recalculate to six sets or confirm a reliable wash.
No laundry | min(7, 7 + 1) = 7 sets | Cover seven wear days under this tool convention.
Worn on departure | One of the total sets | If one is worn, three of the four sets go in the bag.
