Buying rhythm

from 4 government buys since 2017

The government has bought this item about every 1.6 years (very regular, gaps vary ±30%). Last buy Dec 8, 2022. If the rhythm holds, the next one falls between Nov 1, 2023 and Aug 18, 2025: a buy is overdue by the usual rhythm.

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.
