Description
Compare a supplied refresh age with a maximum allowance.
Business metrics depend on event definitions, time windows, revenue and cost bases, and reporting scope. Observed sales during stockout do not by themselves verify latent demand, while a return contribution depends on which costs were already recognized. Local flags and signed balances are not a complete profitability or causal analysis.
Compare a supplied refresh age with a maximum allowance.
When to use this tool
Use Data Refresh Staleness Excess when you already have ageMinutes, allowedMinutes and need to compare a supplied refresh age with a maximum allowance.
How to use the tool and how it works
- Enter ageMinutes, allowedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read excessMinutes, stale. Inspect stale before interpreting the associated values.
Require age/allowance>=0; excess=max(0,age-allowed), stale=age>allowed.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| ageMinutes | Age Minutes | Required. Finite number; minimum 0. |
| allowedMinutes | Allowed Minutes | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| excessMinutes | Excess Minutes | Required. Finite number. |
| stale | Stale | Required. Boolean. |

}Limitations and assumptions
- Equality is not stale. No timestamp, refresh, data accuracy, actual service condition or suitable freshness requirement is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Reconcile source transactions, inventory and cohort records with the full metric definitions. Use complete forecasts, accounting and study designs where needed; individual contributions and supplied scenarios do not establish performance or causal effects.
