What does the fluency meter measure?

Does anybody know what the new fluency meter is claiming to measure? Percentage of what? How is the percentage calculated? What is the point of this number?

Mine has been stuck since I've had it so mine doesn't measure much of anything.

I have 54 in French and 2 in Italian. Neither has changed for me. I think it's pretty bogus.

Thank you. I'm not sure this answers my questions, but here are the words of the Duolingo Team: "This is exactly what it sounds like: our estimate of your fluency in the language you're learning. It is calculated based on what words you know, how important those words are, how well you know them, and how likely you are to forget them. It will increase over time as you learn more words and strengthen your skills, but it will decrease if you don't keep up your strength. Since our goal is for this estimate to be as accurate as possible, be aware that finishing your tree won't get you to 100%. We're constantly working to improve how much Duolingo can teach you, and we hope that providing this insight into your progress will be both informative and encouraging."

I just wonder what the point of this A/B test is. Are they testing to see if people with the fluency meter use Duolingo more? Are they testing to see if it makes people work harder or advance more quickly?

The A/B test is over and everybody has it now. Apparently it has had some positive effect on usage. See this thread for more: https://www.duolingo.com/comment/8981125$comment_id=8988057
