Read the explanation
The default audit assumes eight invoice hours weekly, four weeks per month and twenty eight dollars hourly labor. Its invoice savings are eight hundred ninety six dollars. The lead formula assigns point zero one five recovery per delay hour. Four hours means six percent of one hundred twenty leads, multiplied by four hundred fifty dollars per job, giving three thousand two hundred forty recovered revenue dollars. Bars use point zero five pixels per assumed dollar. This is a deterministic scenario assumption, not observed conversion loss, actual revenue, empirical labor reduction or a calibrated relationship between response speed and sales. Lead values and subscription costs are page fixtures, not current market quotes. Adding labor eight hundred ninety six and lead revenue three thousand two hundred forty gives monthly benefit four thousand one hundred thirty six. Annual gross is forty nine thousand six hundred thirty two. Subtracting setup three thousand forty and twelve subscription payments of one thousand five hundred sixteen, totaling eighteen thousand one hundred ninety two, leaves twenty eight thousand four hundred. Bars compare annual gross and net at point zero zero four pixels per dollar. The field first year net ROI is an absolute currency amount, not a percentage return. It combines revenue with labor value and does not include delivery costs, collection risk, displaced tasks or uncertainty unless represented in the assumptions. Payback divides setup by annual gross benefit divided by fifty two weeks, about three point two weeks. It does not subtract recurring subscription fees from that denominator, so the caption is not full net cost breakeven. When all recipe benefits are off, the denominator is zero and the code leaves payback at zero weeks rather than marking it unavailable. Bars count displayed three point two and zero at fifty pixels per week, without treating zero as immediate repayment. Missing Chart throws at initialization before input or export listeners bind. A native lead slider edit therefore leaves the three thousand two hundred forty caption unchanged, and no actual JSON download occurs offline. The video preserves original canvas allocation and source links while explaining intended math as counterfactual, not a successful live audit or public publication.
