Does anyone know of any research or statistics around edit summary https://en.wikipedia.org/wiki/Help:Edit_summary usage on Wikipedia? All I could find in a quick scan was some statistics from 2010 ( https://meta.wikimedia.org/wiki/Usage_of_edit_summary_on_Wikipedia). I'm curious if anyone has more updated statistics, or, even better: a more thorough analysis of how edit summaries are used by editors -- i.e. how complete they are, to what degree they represent the "what" vs. the "why", how often they are misleading, etc.
Best, Isaac
