In a community-wiki answer which I edited recently, I added one hyperlink, added one comma and removed another. From that time, I’ve been reported as the main contributor to the answer, although the changes I made were pretty small.

I find this devaluing the original author’s contribution…
The page Edit community wiki in the Help Center says:
community wiki posts show the editor with the highest percentage of the remaining post in the current version in the author field.
And the accepted answer to What does the % in the Community Wiki box mean? says:
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.
So I am called “the most prolific editor” because I edited something (although a little bit) in all paragraphs? Are the changed lines interpreted as lines of code, ending with the newline character (paragraphs in fact), and not the lines displayed in browser?
One more thing, the page says 2 users 56%
. Where are the remaining 44%? Only two users have been involved in the post’s history, so I’d expect their contribution to be 100%.
