Description
Measure a supplied toy-sharing turn gap and overlap amount.
Developmental records distinguish calendar age, supplied age corrections, observation states, assent and privacy choices. A corrected age can be negative under supplied assumptions, and a missing response differs from an observed zero. A display mask changes presentation without protecting the underlying record.
Measure a supplied toy-sharing turn gap and overlap amount.
When to use this tool
Use Toy Sharing Single Turn Gap when you already have previousTurnEndSeconds, nextTurnStartSeconds and need to measure a supplied toy-sharing turn gap and overlap amount.
How to use the tool and how it works
- Enter previousTurnEndSeconds, nextTurnStartSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGapSeconds, overlapSeconds. Use the output convention below.
Return nextTurnStart-previousTurnEnd and max(0,previousEnd-nextStart) in seconds.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| previousTurnEndSeconds | Previous Turn End Seconds | Required. Finite number. |
| nextTurnStartSeconds | Next Turn Start Seconds | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGapSeconds | Signed Gap Seconds | Required. Finite number. |
| overlapSeconds | Overlap Seconds | Required. Finite number. |

}Limitations and assumptions
- Overlap corresponds to a negative gap; equality gives zeros. No turns, sharing, behavior, social development or supervision needs are observed or 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 the complete observation or assessment method, age convention and consent context. Review source records and data protection together; local counts, labels and geometric measurements do not establish development, diagnosis or appropriate support.
