It keeps on saying I've gained a new percentage of fluency more often than it usually does, but it's just staying at 44% and not progressing more towards 100%. Anyone else having this problem?
Your fluency score at the moment is 0.44926689537833464. A slight increase can take it to 45% while a slight drop will bring it back to 44%. That's why you see if fluctuating so much.
The number you gave as an example was just an example, right? Cause I would love to see a more descriptive fluency score but don't think it's possible.
It was an actual number for the OP at that point. You can find this in the user information as mentioned in writchie4's post. It's a continuously decreasing value. For OP, the current value stands at 0.44902179532663045.
