Buying rhythm

from 5 government buys since 2020

The government has bought this item about every 9 months (regular, gaps vary ±36%). Last buy Aug 16, 2023. If the rhythm holds, the next one falls between Jan 4, 2024 and Oct 14, 2024: 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.
