Description
Separate recorded time, observed wear time, and a missing-time wear upper bound in a supplied diary interval.
Foot and footwear research uses geometric dimensions, contact cells, forces, and measurement records. A length margin, normalized difference, or contact share has a specific measurement basis and can omit important three-dimensional or sensor effects. Arithmetic on supplied observations is separate from a validated clinical assessment.
Separate recorded time, observed wear time, and a missing-time wear upper bound in a supplied diary interval.
When to use this tool
Use Podiatry Diary Wear Interval Completeness when you have supplied foot, footwear, bench, or recording data and need this measurement or record-support calculation.
How to use the tool and how it works
- Enter recordedMinutes, missingMinutes, offDeviceMinutes, totalMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read observedWearMinutes, observedFraction, possibleWearUpper. Use the output convention below.
Require positive totalMinutes, nonnegative recordedMinutes and missingMinutes with their sum no greater than totalMinutes, and offDeviceMinutes within recordedMinutes. Return observedWearMinutes=recordedMinutes-offDeviceMinutes, observedFraction=recordedMinutes/totalMinutes, and possibleWearUpper=observedWearMinutes+missingMinutes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordedMinutes | Recorded Minutes | Required. Finite number; minimum 0. |
| missingMinutes | Missing Minutes | Required. Finite number; minimum 0. |
| offDeviceMinutes | Off Device Minutes | Required. Finite number; minimum 0. |
| totalMinutes | Total Minutes | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| observedWearMinutes | Observed Wear Minutes | Required. Finite number. |
| observedFraction | Recorded minutes divided by total minutes, not wear minutes divided by total. | Required. Finite number. |
| possibleWearUpper | Possible Wear Upper | Required. Finite number. |

}Limitations and assumptions
- ObservedFraction measures recording completeness rather than wear share. Unclassified minutes outside recorded plus missing are not included in possibleWearUpper, and diary accuracy is not 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use a documented measurement protocol with calibrated equipment and appropriate geometric or contact models. Broader interpretation requires assessment of the underlying observations beyond one length, ratio, or support flag.
