Buying rhythm

from 4 government buys since 2022

The government has bought this item about every 1.7 years (regular, gaps vary ±49%). Last buy Apr 1, 2026. If the rhythm holds, the next one falls between Dec 3, 2026 and Apr 6, 2028: 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 122 days" caught the actual next buy 42% of the time across 16,870 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.
