Buying rhythm
from 8 government buys since 2021
The government has bought this item about every 2 months (irregular, gaps vary ±184%). Last buy Mar 19, 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 151 days" caught the actual next buy 31% of the time across 21,161 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.
