going from 51 % to 50 % fluent??
Yesterday, after a long wait, I finally went from 50 % fluent to 51% fluent.
Today when I typed in my home page, I saw it go back to 50%. I am curious. What is happening?
The fluency score will decrease/increase from time to time, depending on what you've reviewed/practiced; here's a detailed Help Center article explaining what the fluency score means:
Your percent will always decrease a bit over time. Since you just made 51, keep working and it will return soon.
