A verification standard, not a tool.
PropEaze measures maintenance outcomes to a settlement grade: the bar a counterparty would demand before accepting a number as fact. Vendor scorecards report averages. A settlement standard has to survive being a wrong in public, so the predicate is stated in advance, measured conservatively and graded on live tickets.
The predicate
Verified callback rate, Wilson 95% CI upper bound below 5%, sustained on live tickets.
Denominator: verified completions across the cohort, pooled, minimum 1,500. No single operator over 45% of the pooled denominator. Callback is any return visit to the same unit for the same fault within 30 days of verified completion. Callbacks count against us whether or not the vendor agrees.
In plain terms: fewer than 5% of verified completions come back as repeat work, and we hold ourselves to the pessimistic end of the confidence interval rather than the point estimate, the same convention an actuary would apply. The guarantee activates when the predicate clears. Until it does, the rate still only applies to savings that verify.
Published methodology. Graded on your tickets, not ours.
