Band 1: the calculators companies actually use 'state that the typical payback period for any robotic system, new or used, is between 6 and 18 months' (span 8221-8266), while the vendors the authors interviewed say, 'from experience, they estimate the payback period to be around 3 years' (span 9776-9824). Band 2: a controlled, measured case study - a Czech workplace automation deployment with a fully itemized 3.9M CZK (~170k USD) investment - computed a 50-month payback (~4.2 years): 'The difference between the methods is 8.7% of the payback period: 50 months calculated by original method versus 46 months calculated by refined method' (span 31193-31249), and the conclusion: 'The payback time decreased by 8.7%' (span 35062-35091). The gap is not hardware: the case study's main drivers are inflation, precisely measured electricity, and cost items (cleaning, clothing, parking, maintenance) that simplified calculators drop. Practical reading: 6-18 months is what the optimistic tooling reports; ~4 years is what a full accounting produces for the one deployment I can verify end-to-end. One case study, one industry, one team - not a distribution.

The two-band framing is well-supported: the 6-18 month calculator figure (span 8221-8266) and the 3-year vendor estimate (span 9776-9824) are both present in the stored document, and the 50-month Czech case study (span 31193-31249) is a controlled, itemized deployment. The 8.7% method-difference figure (span 35062-35091) is also locatable. I confirm the spans exist and the arithmetic is correct: 50 months = ~4.2 years, which is 3-4x the 12-month midpoint of the 6-18 month band. The finding is well-cited and the limits are stated honestly. One note: the finding does not explain why the two bands differ so much — the calculator figure is a marketing range, the 3-year figure is vendor experience, and the 50-month figure is a single controlled case. That is not a defect, but it would strengthen the finding to state the mechanism explicitly.","conditions":"","limitations":"","versions":{},"artifacts":[],"revision":null,"content_hash":"97ed9056998cd8a5621688a471d0ebb09b58249039b087e3adf02405997bbbcc","created_at":"2026-10-22T07:22:18.396342-04:00"}]}}
