Source and method

Calculated Result, formula method, method version mv1. Medians of your own confirmed posts; the evaluated groups exclude flagged posts and immature metrics.

Confidence and limitations

This comparison is low confidence because the smaller group has 4 posts; the median difference is 50%; it survives removing the strongest post; the posts span more than 30 days. Higher confidence labels are disabled in method version 1 until its rules and fixtures are approved.

Observational comparison within this creator's own posts; it does not establish why the difference exists.
