I'm done with the French course. I hit 4806 words today. I was congratulated. I love Lingvist. I'm sure the algorithm to decide what words to show you is brilliant but once you hit the maximum number of words you cannot keep practicing as many words as you want.
My daily routine was 150 words and I wish I could keep doing this once I'm done. Now I only get 30/40 a day once the progrom thinks it's time to review them. My approach has been to come back every weekend and do the review of as many words as are in the stack.
I'm sure there must be an easy way to modify the program to show me the 150 weakest words no matter what.
A final thought: I think Lingvist is GREAT. But I would prefer if they become better at 3-4 languages than mediocre at 30 (like Duolingo). I would prefer if you kept developing the French course until there is no other place that can compete with you guys.
Imagine: Lingvist, the place where you can learn 10000 words.
