Description
Calculate a supplied session end-minus-start gap.
Clinical and training records can preserve source-qualified point names, study design codes, device wording and reported hours. A record token does not identify an anatomical point or establish treatment effectiveness, and a printed expiry-date gap does not verify sterility or equipment suitability.
Calculate a supplied session end-minus-start gap.
When to use this tool
Use Acupuncture Session Start End Gap when you already have startMinutes, endMinutes and need to calculate a supplied session end-minus-start gap.
How to use the tool and how it works
- Enter startMinutes, endMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return endMinutes-startMinutes with signs preserved.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| startMinutes | Start Minutes | Required. Finite number. |
| endMinutes | End Minutes | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- Reversed times and negative durations are accepted as discrepancies. No actual care, appropriate duration, efficacy or safe procedure is 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 original clinical, research, training and manufacturer records with the appropriate professional assessment. Local labels and calendar arithmetic do not guide treatment, locate points, select devices, establish efficacy or verify safe practice.
