Frequently asked questions
Does this replace product analytics?
No. It is a manual first-pass calculation; analytics tools are needed to collect and investigate live data.
Why use absolute changes?
Large positive and negative movements can both signal a reporting change, release effect, or behaviour worth understanding.
What is a good baseline?
Use a comparable period with the same definition, product state, and enough volume to reduce noise.
