About MDEK1001 Quality Factor

I used to 1 Tag and 4 Anchor to detect the position.
Here is the measurement result.

I have two questions about the meansurement results.

1.For the red part of the measurement result,
Please tell me in detail how this quality factor was derived and how it was calculated.

2.For the blue characters in the measurement results,
I understand that it represents the distance measurement accuracy between Anchor and Tag, but why are all 100? Is the distance measurement between Tag and Anchor perfect? If not, please tell me what the blue text represents.

I wanted to post it as a new topic, but I couldn’t select an optional category and couldn’t send an email so I sent it separately.
