Since there are not alot of editors, or actual edits, I suggest Full Recent Changes be allowed to provide additional history, perhaps up to 14 days or 30 days. Note my question on Quick Question (posted Monday) may not be well noticed after this Thursday.
So I experimented
The drop down box provides a scroll wheel with 24hours, 48hours, 3days, 4days, or 5 days.
The URL for a 5 day search is as below
https://senseis.xmp.net/?page=FullRecentChanges&frcSortOrder=lastmodified&frcDuration=5&frcFilter=
My clever editing of the URL to show 12 days, did not work.
https://senseis.xmp.net/?page=FullRecentChanges&frcSortOrder=lastmodified&frcDuration=12&frcFilter=
But it showed the 3 day response, obviously some hard coded default response to incorrect URLs.
