Buying rhythm

from 4 government buys since 2026

The government has bought this item about every 2 months (very regular, gaps vary ±17%). Last buy Sep 23, 2026. If the rhythm holds, the next one falls between Sep 28, 2026 and Dec 27, 2026: a buy is due about 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.
