I've noticed that after you post something (an answer, comment, or question) then press "Edit" soon after and make a change, there is no "Edited
I have a few questions about this: How long can you wait before editing so the change log doesn't show? (the longest I've seen so far is 2 minutes.) Can moderators/editors etc see the change log even when this happens? Does this also have something to do with if your comment is followed/answer or question commented on?
EDIT: Testing it out, I edited it after under a minute has passed
