Buying rhythm

from 9 government buys since 2017

The government has bought this item about every 12 months (regular, gaps vary ±55%). Last buy Nov 17, 2025. If the rhythm holds, the next one falls between May 29, 2026 and Jun 19, 2027: 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 15,552 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.
