Buying rhythm

from 5 government buys since 2018

The government has bought this item about every 7 months (regular, gaps vary ±59%). Last buy Aug 12, 2021. If the rhythm holds, the next one falls between Dec 16, 2021 and Aug 25, 2022: a buy is overdue by the usual rhythm.

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.
