Duo please remove the fluency meter - it's meaningless
To the developers of duo - please remove the fluency meter. NOBODY understands what it measures, how it measures, etc. The numbers don't seem to reflect any level of activity that the users are doing. How many times do we need to read posts where "I gilded my tree and my fluency went down!"?? Fact of the matter is fluency is a measure of talking speed which is really hard to measure when most activities are typed. Worse yet, the mic exercises can be turned off. How on earth do you measure fluency when the one thing NOT being measured is speaking? The meter means nothing.
If you must give us some sort of feedback on our progress, how about something that is quantifiable? Like a measure of tree completion? A message "You are 27.3% completed in Spanish"... Maybe replace fluency with lessons remaining? "You have completed X lessons out of Y total. You have Z lessons remaining." How about a percentage of subjects that are golden? "Your completed lessons are 73% golden." You see, those are all scripts that leave NOTHING to wonder and they remove all doubt. Since the advent of the fluency meter there is only confusion and the resulting number means NOTHING.
Please remove this pointless feature.
