Description
Compare recall timing with source-record creation.
Consumer-study records can describe exposure, recall, option availability and purchase-value bases. Local record arithmetic preserves a supplied study or billing convention without measuring preferences, establishing memory accuracy or determining consumer rights.
Compare recall timing with source-record creation.
When to use this tool
Use Purchase Recall Source Gap when checking a supplied consumer-record, recall-window, choice or basket convention.
How to use the tool and how it works
- Enter purchaseAt, recallAt, recordCreatedAt. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read recallDelay, recordDelay, sourceTimingGap. Use the output convention below.
Compare recall timing with source-record creation. Require recallAt and recordCreatedAt >= purchaseAt; return both delays from purchase and sourceTimingGap = recallAt-recordCreatedAt.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| purchaseAt | Purchase At | Required. Finite number. |
| recallAt | Recall At | Required. Finite number. |
| recordCreatedAt | Record Created At | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| recallDelay | Recall Delay | Required. Finite number. |
| recordDelay | Record Delay | Required. Finite number. |
| sourceTimingGap | Source Timing Gap | Required. Finite number. |

}Limitations and assumptions
- A later or earlier record is not evidence of accurate recollection or source reliability by itself.
- 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
Use actual study data, validated measurement methods and applicable merchant/consumer rules for substantive behavioral or transaction conclusions.
