What action to take based on the FSRS Calibration Graph?

Hello, I ran the FSRS optimizer for my Anki deck and the results look strange to me:

It says, that if the blue line is higher than the orange one then FSRS has underestimate the retention. I see that is the inference but what can I fix to ensure that the retention with FSRS still remains high?

Thanks for reading it.

You doesn’t need to do any actions. Because the Calibration Graph is used to evaluate the model, not your memory.
