Description
Return weighted repeated-duration total.
Participant time, compensation and renewal timing depend on explicit assumptions about visits, expenses, comprehension and applicable rules. A supplied rate or elapsed-time threshold can support bookkeeping while fair compensation, accessibility and valid consent require a broader contextual assessment.
Return weighted repeated-duration total.
When to use this tool
Use Participant Burden Interval Sum when checking the stated research payment, burden, reading-time or renewal convention.
How to use the tool and how it works
- Enter durations, repetitions. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read totalDuration. Use the output convention below.
Return weighted repeated-duration total. Require aligned duration/repetition arrays with nonnegative durations and whole repetitions; totalDuration is their dot product.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| durations | Durations | Required. Array of finite number; minimum 0; maximum items 256. |
| repetitions | Nonnegative whole repetition counts, aligned to durations. | Required. Array of safe integer; minimum 0; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| totalDuration | Total Duration | Required. Finite number. |

}Limitations and assumptions
- Repetitions must be nonnegative whole counts; overlapping activities, actual burden and ethical adequacy are not assessed.
- 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 participant-centered evidence and the original protocol and consent process; review payment, accessibility and renewal choices with the responsible ethics and professional teams.
