I have experienced it a few times in editing a question, and I have just found an example.


As far as I understand, your edits, no matter how many times you edit within 5 minutes after your initial post or last edit, are supposed to be rolled into the previous revision, not appearing as a new revision history as the above link indicates. The above link shows only 3-minute interval.

Is my understanding incorrect? Have I missed something?

    According to this FAQ, near the bottom, there are only 3 exceptions to the "grace period edit folding". The only one which seems potentially applicable to this case is "A comment has been added to the post since the previous revision by anyone other than the editor". Now, the only comment I currently see on that post came too late to trigger this exception, but maybe it's possible there was an earlier comment which did trigger it, and later was deleted? Possibly because the edit addressed the concern?

    I commented with a suggestion for improving Eilia's answer. She then immediately improved the answer and thanked me in a comment. Then I removed my comment and they theirs.

    I have found the "time limit" to be quite variable. Anything under 3 minutes seems OK, but above that it's iffy at best. I suspect this has to do in part with the mechanics of timekeeping in Javascript.

  • @HotLicks: I doubt the grace period is implemented in JavaScript; rather, I'm pretty sure it's applied on the server-side when the edit is submitted.

    @ruakh - I've seen claims made that you can bypass the grace period by hacking the script.

  • @Josh61 I am very disappointed at the responses. That's why. I'm on your side if you want to convert ELU to general reference and opinion-based Q&A site, but as long as there are guidelines, I think it is the right thing to do to follow the guidelines. It's a shame that we are discussing the issue based on such a low-quality question. That's what I felt.

  • @Josh61 I respect your opinion and undeleted the question.

I thought about deleting the question, but decided to leave the link with brief summary as it could be useful for current and future users.

@DanBron's comment has the answer. According to How does editing work?,

If a comment has been added to the post since the previous revision by anyone other than the editor, the five-minute grace period for editing will not be applied and the edit made after the comment will be shown as a separate revision history (even if it was made within the five-minute grace peirod).

I think two comments were added to the answer before the two edits were made (and later deleted). That's why the link shows the two revision histories even though the intervals are less than five minutes.

I started to find a duplicate in Meta Stack Exchange and found a question related with five-minute grace period in editing a question.

Reset question grace period once an answer has been posted.

According to Shog9's answer:

Edits will be rolled into the previous revision if the previous revision was created by the same author and none of the following conditions are present:

  • The previous revision was created 5 minutes or more in the past

  • A comment has been added to the post since the previous revision by anyone other than the editor.

  • An answer has been added to the post since the previous revision

  • The previous revision was a rollback

  • The new revision is a rollback

  • It's a good question to keep around, I didn't know these exceptions. Maybe you could make the question more general, like under what circumstances will edits not be combined together? Jun 19, 2016 at 1:08
  • Apart from the pure technical aspect, but how can one or two minutes difference impact (if it does at all) the quality of questions or answers that is at the heart of ELU?

    This is indeed what happened. The comments which caused the observed phenomenon have been removed (but mods can still see them, and there's a comprehensive timeline as well).
