Buying rhythm

from 4 government buys since 2017

The government has bought this item about every 3.4 years (regular, gaps vary ±37%). Last buy Aug 3, 2026. If the rhythm holds, the next one falls between Feb 13, 2028 and Mar 9, 2031: next buy not yet due. 1 solicitation is open right now.

How well this works: for regular items, "next buy about one typical gap after the last, give or take 121 days" caught the actual next buy 42% of the time across 15,953 past buys, against 22% 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.
