Definitions
Fragment of a discussion from Talk:Editor Trends Study
Dear Pavlosh,
To clarify the definitions: 1) The two metrics are unrelated. So yes a person can qualify for both in the same month (and Anonymous authors are not included).
2) We intend only to include edits from namespace 0 as that's the core content.
3) If time permits, we will use different thresholds to see how robust our findings are.
The suggested approach is consistent with Erik Zachte's stats.wikimedia.org approach.
