Buying rhythm
from 5 government buys since 2020
The government has bought this item about every 12 months (loose, gaps vary ±87%). Last buy Jan 15, 2026. The gaps are too uneven to put a window on the next one. 1 solicitation is open right now.
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.
