We already have another excellent question on CV.SE setting out editing dos and don'ts, but that mostly focuses on the limitations that apply to editing other people's posts, rather than the substance of what are some good practice for editing to improve a post. The purpose of the present question is to elicit some general recommendations on how to improve posts on CV.SE using standard editing methods.This will be of use for the benefit of both original posters and editors. We have many excellent contributors here who have learned a lot of good ways to structure and format their posts, and edit to improve the clarity, so I think it would be valuable to list some proposed "best practices" or tips for other users.
(Caveat: I am aware that there are different considerations depending on whether one is formatting one's own post or a post written by another user. In the latter case, it is established practice on CV.SE that edits should not change the substance of the original post, or even correct statistical errors in the original post. Advice on "best practices" should take this as given.)
