Buying rhythm
from 11 government buys since 2017
The government has bought this item about every 4 months (irregular, gaps vary ±116%). Last buy Aug 18, 2025. The gaps are too uneven to put a window on the next one. 1 solicitation is open right now.
How well this works: for irregular items, "next buy about one typical gap after the last, give or take 152 days" caught the actual next buy 31% of the time across 21,749 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.
