Buying rhythm

from 5 government buys since 2016

The government has bought this item about every 2.0 years (regular, gaps vary ±48%). Last buy Jul 27, 2026. If the rhythm holds, the next one falls between Oct 10, 2027 and Mar 8, 2030: next buy not yet due.

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.
