Buying rhythm

from 16 government buys since 2018

The government has bought this item about every 5 months (regular, gaps vary ±55%). Last buy Jan 8, 2026. If the rhythm holds, the next one falls between Apr 7, 2026 and Sep 30, 2026: 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.
