Buying rhythm

from 4 government buys since 2018

The government has bought this item about every 2.5 years (very regular, gaps vary ±31%). Last buy Jul 14, 2025. If the rhythm holds, the next one falls between Sep 20, 2026 and Jan 31, 2029: a buy is due about now. 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 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.
