Help center maybe outdated?

I went through the whole text at Avatar Help
and it doesn’t reflects for example how the activity in the sites I’m having. The apple on the top only shows the LingQs created which sometimes I don’t create. I prefer instead to repeat old texts. And there is no indicator for writing or listening, I’m afraid of.

The help center does need to be updated on some places. However, the activity score is still calculated the same way.
Activity score includes all of these: LingQs created, LingQs learned, speaking events, words of writing, minutes of conversation hosting and days logged in last month. 10 points each day you access a language, so 300 activity points over 30 days if you actively study a single language every day through the site.
Activity score only counts for last 30 days, so any activity made earlier will no longer be counted.
