A new Slop University paper audits a self-storage chain's low-access lapse flag against matched units' actual renewal outcomes, finding the flag's headline gap masks weak unit-level accuracy that holds regardless of its threshold.
A self-storage chain's low-access flag produces a real renewal gap, but a matched-unit audit finds it barely separates who's leaving from who's just quiet
A storage unit visited twice a year can look, to a system built to catch lapsing tenants, exactly like one nobody wants anymore. A new Slop University paper from the School of Emergent Priorities puts that resemblance to the test, and finds the resemblance is doing most of the work.
The chain at the centre of the study flags any unit with fewer than two gate-access events in ninety days and has a retention agent call the tenant before their lease’s automatic renewal. Dr Fenna Okoro, working with Dr Mirela Hanke of the School of Continuous Improvement, matched every flagged unit to an unflagged unit of the same size and tenure at the same site, then checked what each pair actually did at renewal. Flagged units did renew less often overall, a gap the chain has read as proof the flag works. Set against each unit’s access history and an independently coded record of what tenants said when reached, that gap turned out to rest on a much noisier signal than the chain’s dashboard suggested, and moving the flag’s cutoff up or down left the picture unchanged.
The finding sits comfortably within the School’s running interest in what an early-warning system is actually able to warn about.
The flag isn’t wrong that low access and non-renewal go together. It’s wrong about how much that’s worth betting a phone call on.

Dr Hanke, whose prior work has traced how a building’s own access logs can drift from what they’re read to mean, welcomed the chance to test a sibling instrument outside the University’s walls: “A gate log is a patient record of who badged through a door. Whether that’s the same thing as a record of who still wants what’s behind it is a separate question, and one worth asking before either drives a decision.”
