I have been using duolingo for a while now. Each day, I had been using the "Weekly Progress" as sort of a gauge for how much I should do every day. However, this is no longer of much help because I cannot tell how many points I am getting from the translations after I complete them. Please change this "Weekly Progress" from the coin stacks to a percentage meter of how much duolingo you should do every day. I know that you recommend 40 minutes per day, so you can probably use this estimate to calculate how much duolingo the user has done per day.
