How does the deviation calulated by "Find Circular Edge Tool" come?

[Purmpol]

I'm measuring quality of circularity for ring product by using the deviation in "Find Circular Edge Tool". And I need to explain customer how does the deviation come.

Could someone tell me what is the formular to calculate this?

Thanks.
