Hi Goran, We'll keep an eye toward consistency, but we have not made the data extraction into a fully automated process. We identified 3 columns that had slightly different names and we'll fix them: overall SIZE rank (2020) vs. overall size rank (2018, 2019) second month editor retention (2020) vs. second-month new editor retention (2018, 2019) monthly structured discussions messages (2020) vs. monthly structured discussions (Flow) messages (2018, 2019) The "project code" column was duplicated in 2020; the duplicate has now been removed. Finally, in 2019 we had added 3 new columns that we hadn't tracked in 2018: content pages, cumulative content edits, edits per content page. Please be aware that we may add or change columns in the future as needs evolve. Warm regards, Kate On Tue, Feb 23, 2021 at 12:37 PM Goran Milovanovic < goran.milovanovic_ext(a)wikimedia.de&gt; wrote:
