Description
Return funnel closing count and net forward movement.
Business timing and cohort summaries depend on event origins, bucket boundaries and the treatment of incomplete records. A time difference or bucket label is a supplied record convention rather than proof of customer behavior, completed service or future retention.
Return funnel closing count and net forward movement.
When to use this tool
Use Funnel Back Track Count Delta when checking the stated business timing or cohort convention.
How to use the tool and how it works
- Enter opening, forward, backward, abandoned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read closing, netForward. Use the output convention below.
Return funnel closing count and net forward movement. Require nonnegative whole opening/forward/backward/abandoned and forward+abandoned <= opening+backward; closing = opening+backward-forward-abandoned, netForward = forward-backward.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| opening | Opening | Required. Safe integer; minimum 0. |
| forward | Forward | Required. Safe integer; minimum 0. |
| backward | Backward | Required. Safe integer; minimum 0. |
| abandoned | Abandoned | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| closing | Closing | Required. Safe integer. |
| netForward | Net Forward | Required. Safe integer. |

}Limitations and assumptions
- This is supplied event-count bookkeeping, not actual entity deduplication, transition validity or causal conversion analysis.
- 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 complete event records and a defined cohort/period policy; evaluate commercial performance and uncertainty with appropriate complete analyses.
