I flagged an answer as "Not an answer". I saw later that OP changed the answer and now it is completely meaningful and appropriate. But I am wondering the edit is not showing. How is it possible?
If you edit a post within 5 minutes of the latest version (that you submitted) then it will count as one edit. This is so that users can fix typos and formatting issues without having too many revisions.
Why is it bad with many revisions? Well after 10 revisions on a question it will automatically become a community wiki. On a community wiki you do not earn any reputation from it. So from not having too many questions becoming a community wiki automatically there's a 5 minute fix time.
Hope that is what you asked for.
