Thing is, I do less than 1 lesson per day. Probably 3 lessons per two weeks. Meaning that I press Practice button about 100 times in that two week period. After about 40 days, I went back to go through some of the previous lessons, given their new Crown update, and realized I haven't seen some of the words at all. Despite having around 400 words learned so far.
