Your numbers, our arithmetic, nothing hidden. Triage time recovered comes from the false-positive reduction you expect (calibrated detectors, composite cases, disposition macros); exam-prep savings assume 70% of the hours go away when the surveillance exhibit, audit packages and methodology are generated rather than assembled.
Not counted: the cost of a surveillance finding an examiner makes before you do, and the engineering time a build-your-own path consumes (itemized here). Design partners see a different price — pricing.
