This question is about the community wiki info-box in the bottom right corner of questions: What does the percent number refer to?

The example quoted is the The Definitive C++ Book Guide and List.

And do I get the rest right?

  1. The question was reviewed/edited 95 times
  2. 51 users were involved
  3. The percent number I can't assign
  4. Last editor (here: sbi)
  • I think it's the amount contributed by the author with the most contributions, which is the one shown in that author box (@sbi in the C++ books question). See the description: Additionally, community wiki posts show the editor with the highest percentage of the remaining post in the current version in the author field Jul 24, 2013 at 19:42
  • @Mureinik what is a revived question? :) May 31, 2017 at 17:01
  • @Mureinik no worry, happens even to SE employees... :-D Jun 1, 2017 at 8:15

4. Last editor

It's not the last editor, it's the most prolific editor, based on a very naive calculation involving lines of the post that were changed.

The percentage is the amount of content attributed to that editor, so in this case it's saying that sbi's content is responsible for 23% of the visible post.


It's a rough measure of the percentage contributed to the post by the editor that made the largest contribution to the question.

(say that five times fast)

    I can't. It's too long to fit in the comment box.
