XP Points totals
Once again, my Fluency level in French has been reduced by Duo. Monday last, I reached 68% fluency. Tuesday and each day since, this is shown as 67%. This, in spite of many hours of successful work since Monday. DOES anyone else experience this?
Note that your XP total has nothing to do with your fluency rate. Every time you do an activity you get a certain number of XP. You won't lose XP unless you delete that course. Your level is decided from that.
Your fluency rate is calculated separately. I presume it has to do with how many different words you know and how "strong" they're listed.
