Word strength improvement
Today I have got several words wrong consistently, however they still appear at full strength in my vocabulary list. Surely it would make sense to reduce the strength of words I consistently get wrong so I get more practice at them?
I agree. There are some words I forget again and again, but they appear no more often than other "old" words.
I also notice a lot of inconsistencies between strength levels. The unit may have 3 bars while the Practice button inside only 2 bars and the lessons 4 or 3 bars. Where does 2 come from, I wonder?
