Method reference
Diagnostic and calculator methods § 6. K01 CAC and tranche comparison
§6
This ratio is not decision-reliable because the plausible effect includes zero.
§9
No supported positive incremental acquisition; no negative-CAC success
§6
If only attributed data are available, label the output Attributed CAC and state that it does not isolate causality.
§6
This is propagation of a supplied range, not a newly calculated confidence interval.
§7
If evidence is observational or forecast, label the result a scenario/association, not causal profit.
§7
The rate difference is an estimate, not an observed count of individually “saved” customers.
§7
Forecast/rollout inputs retain their scenario label and are never presented as realised cash.
§8
Show signed loss plainly; no cosmetic success state
§7
The tool validates completeness and labels; it cannot verify the supplied method or prove causality.
