Buying rhythm

from 5 government buys since 2016

The government has bought this item about every 2.3 years (very regular, gaps vary ±26%). Last buy Jul 15, 2026. If the rhythm holds, the next one falls between Sep 24, 2027 and Feb 12, 2030: next buy not yet due.

How well this works: for very regular items, "next buy about one typical gap after the last, give or take 112 days" caught the actual next buy 49% of the time across 5,054 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.
