Description
Return proxyAt-selfAt as a signed gap.
Research schedules and activity records use numeric intervals, pauses, and overlap conventions. The same endpoints can produce different summaries depending on whether simultaneous activities are counted once or separately.
Return proxyAt-selfAt as a signed gap.
When to use this tool
Use Proxy Self Response Time Gap when you need a time-budget or interval calculation in geriatric research records.
How to use the tool and how it works
- Enter proxyAt, selfAt. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gap. Use the output convention below.
Return proxyAt-selfAt as a signed gap.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| proxyAt | Proxy At | Required. Finite number. |
| selfAt | Self At | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gap | Difference on the stated unit and subtraction basis. | Required. Finite number. |

"input": {
"proxyAt": 20,

},
"output": {
"gap": 5
}
}Limitations and assumptions
- Both times use one coordinate and unit; no date parsing, proxy consent, response comparability, or clinical meaning is inferred.
- 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 the full schedule and source timing convention before aggregation. Use an appropriate observational or clinical assessment for questions that duration arithmetic cannot answer.
