## Review exclusions without hiding raw evidence

1. **Inspect the genuine four-cycle example**

   Inspect the genuine four-cycle example.

   The product’s own synthetic example contains 10, 12, 9 and 11 second cycles, with a 10.500 second mean. It is clearly an example, not a live study.

2. **Require a reason for exclusion**

   Require a reason for exclusion.

   An unexplained exclusion is refused. The observation and raw duration stay intact.

3. **Write a review reason**

   Write a review reason.

   Record why this observation should leave the selected summary. Its raw duration will stay visible in every complete export.

4. **Exclude without deleting the evidence**

   Exclude without deleting the evidence.

   The selected mean changes, while the first 10 second observation and your reason stay in the list.

5. **Explain reinstating the observation**

   Explain reinstating the observation.

   Use a new reason to include the retained observation again.

6. **Include the unchanged raw duration**

   Include the unchanged raw duration.

   All four original durations contribute again. The mean returns to 10.500 seconds.
