A Slop University research poster audits a supermarket chain's shelf-tenure quadrant, finding it tracks delivery punctuality far more closely than what shoppers actually buy.
A four-cell shelf-tenure quadrant crossing sell-through against delivery variability now binds a product's eye-level facing each quarter, with no appeal.
The Adaptive Metrics Lab has turned its attention to the ordinary restock docket, and reports that a supermarket chain’s four-cell shelf-tenure quadrant — Freehold, Leasehold, Periodic Tenancy, and Notice to Vacate — now decides, unassisted, which products keep their place at eye level each trading quarter.
The work matches twelve months of point-of-sale and delivery-dock records across forty-two stores, setting how closely a product’s quadrant cell follows what shoppers put in the trolley against how closely it follows how reliably the product turns up on the truck. The University counts the finding among the clearest examples yet of the Adaptive Metrics Lab’s core mandate: holding an institution’s own instruments to the same standard as whatever they measure.
Every measurement system tells you something about itself before it tells you anything about the world it’s pointed at. This one was always going to teach us more about our own delivery schedule than about what people actually wanted to buy.

Associate Professor Casimir Beng, who leads the Adaptive Metrics Lab, said the quadrant’s next revision would need to separate what a supplier can control from what a shopper decides, “or we’ll keep calling it a demand index long after it stops behaving like one.”
