I would have left this to it's misery. apple.stackexchange.com/posts/217890/revisions (and not tried to make it better - it's just bad, so let it be bad since I can't think how to make it useful)
Same for the question - that is probably the best of the three since it removes something that people often do (chit chat) and it really tightens the "ask" - basically letting grammar make it clear what the user did.
Also - once you bumped that old question - it was fine to edit more than one post.
the bumping surfaced it as a dupe which is a big, big help to the site - so A+
If you find all you are doing is edit, then those aren't good enough to sustain your streak.
but - fixing 5 or ten posts over a cleanup session (when you are addressing tags or merging / closing duplicates) that's great.
