Buying rhythm

from 18 government buys since 2017

The government has bought this item about every 2 months (irregular, gaps vary ±115%). Last buy Sep 17, 2026. The gaps are too uneven to put a window on the next one.

How well this works: for irregular items, "next buy about one typical gap after the last, give or take 152 days" caught the actual next buy 31% of the time across 23,072 past buys, against 24% 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.
