Possible bug in iOS app

I'm using the new iOS app on an iPad in French from English with the microphone turned off. When I finish a unit with no errors I get a count of 17 on the strength bar. When I make one error, I get a count of 21. It seems like it should be 18 instead. Bug?

When you make an error, I think Duolingo gives you more questions to make up for that error.


The progress bar moves forward for correct responses. But for incorrect responses it will move backward. So, if you are question number 17 and provide an incorrect answer, it will move one step back and you will need 2 correct responses now to complete the lesson.


17 plus 2 is 19, not 21...
