Description
One limb stance/swing duty factor with an explicitly supplied simultaneous-contact duration, without gait classification.
Specimen measurements and animal observations depend on a defined body part, reference value, unit, and observation window. A mass fraction, size ratio, or timing share summarizes those inputs. The counting and measurement conventions must stay explicit when comparing specimens or records.

When to use this tool
Use Animal Stride Duty Factor One Cycle when you need to compare supplied specimen measurements or observation records under an explicit reference and denominator.
How to use the tool and how it works
- Enter stanceSeconds, swingSeconds, overlapSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read cycleSeconds, stanceDuty, contactOverlapFraction. Use the output convention below.
Sum stanceSeconds and swingSeconds for positive cycleSeconds. Divide stanceSeconds and overlapSeconds separately by that total for stanceDuty and contactOverlapFraction, requiring nonnegative times and overlap no greater than the cycle.1

| swingSeconds | Swing Seconds | Required. Finite number; minimum 0. |
| overlapSeconds | Overlap Seconds | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| cycleSeconds | Cycle Seconds | Required. Finite number. |
| stanceDuty | Stance Duty | Required. Finite number. |
| contactOverlapFraction | Contact Overlap Fraction | Required. Finite number. |

}Limitations and assumptions
- Overlap is supplied and is not subtracted from stance plus swing. These per-cycle proportions do not establish a gait diagnosis, locomotor efficiency, or a species-specific reference.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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 compatible measurements and observation records to verify the chosen denominator and reference before interpreting a specimen comparison.
