Words Learned

Not that it's a big deal, but I wonder how my number of Words Learned can go down. Does duo know how forgetful I am?

I noticed that today, my word count lowered by over 30 words

They must've taken unnecessary words out of the lessons.

I think that they use a special algorithm that takes into account how many times you have seen this word, in how many different forms and how long ago.
