Buying rhythm
from 4 government buys since 2017
The government has bought this item about every 2.2 years (regular, gaps vary ±46%). Last buy Sep 1, 2026. If the rhythm holds, the next one falls between Feb 15, 2028 and Jan 14, 2031: next buy not yet due. 1 solicitation is open right now.
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.
