I just did this review in the First Posts queue, and clicked on "edit" because I was pedantic and wanted to change "should of" to "should have."
When I clicked "edit", I found that I had passed a review audit, and that the question itself had been deemed "high-quality." What confuses me though was that I was under the impression that editing a high-quality post would cause me to fail the audit (since the question would seem to be perfectly fine on its own already).
So then, was I mistaken? If so, what exactly makes it the "correct" thing to do?
