Buying rhythm

from 5 government buys since 2018

The government has bought this item about every 10 months (very regular, gaps vary ±25%). Last buy Jul 15, 2021. If the rhythm holds, the next one falls between Dec 18, 2021 and Oct 26, 2022: 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.
