>I'm not sure how "estimated reading time" works for non-english speakers.

Do you mean people whose native language is not English? I assume it works the same way as for everyone else, i.e. it's always an approximation anyway. I'm not from an English-speaking country, but I'm pretty sure I read faster than the average English native.

The other interpretation is that you mean people who can't read English at all, but in this case I understand even less. They won't be able to read the article, if they don't speak the language. After automated translation, the reading time should be roughly correct again.
