Hello @Lukasz_Gornicki I know @sgupta addressed the difference between active contributors and drifting away contributors here: How are ‘Active’ and ‘Drifting Away’ contributors computed? And when does a drifting contributor become completely inactive? - Learn about LFX / LFX Insights - LFX Community Forums
@Lukasz_Gornicki Quick question, when you were seeing more active contributors over total contributors, do you remember what your time filter was?
Upon checking myself, I see for 1 year you have 1k total contributors and 754 active conributors.
