Buying rhythm

from 5 government buys since 2017

The government has bought this item about every 1.9 years (regular, gaps vary ±43%). Last buy Apr 14, 2025. If the rhythm holds, the next one falls between Apr 26, 2026 and May 21, 2028: a buy is due about 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.
