Buying rhythm

from 5 government buys since 2017

The government has bought this item about every 1.4 years (very regular, gaps vary ±30%). Last buy Aug 31, 2022. If the rhythm holds, the next one falls between Apr 30, 2023 and Aug 28, 2024: a buy is overdue by the usual rhythm. 1 solicitation is open right 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.
