Buying rhythm

from 13 government buys since 2017

The government has bought this item about every 3 months (regular, gaps vary ±54%). Last buy Mar 19, 2020. If the rhythm holds, the next one falls between May 2, 2020 and Jul 31, 2020: 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.
