Buying rhythm
from 4 government buys since 2019
The government has bought this item about every 2.5 years (very regular, gaps vary ±17%). Last buy Aug 27, 2026. If the rhythm holds, the next one falls between Oct 30, 2027 and Mar 8, 2030: next buy not yet due. 1 solicitation is open right now.
How well this works: for very regular items, "next buy about one typical gap after the last, give or take 113 days" caught the actual next buy 48% of the time across 5,157 past buys, against 20% 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.
