What must be true for three-month payback?
Reverse-engineer the operating-cost boundary, then compare it with an explicit scenario. No live hardware price, demand, or revenue data is connected.
Source figures, not verified facts: 100 devices, $59,900 capex, $25k-$30k monthly income, three-month recoupment.
Source scenario ready. Run the stress test.
