Buying rhythm
from 17 government buys since 2021
The government has bought this item about every 2 months (loose, gaps vary ±86%). Last buy Jun 25, 2026. The gaps are too uneven to put a window on the next one.
How well this works: for loose items, "next buy about one typical gap after the last, give or take 136 days" caught the actual next buy 37% of the time across 34,631 past buys, against 24% for a fixed "one year later" guess. A rhythm, not a schedule: DLA buys when stock and demand say so. Every item due for a buy now.
