Guidelines for Recover Original Detail

Every so often I have to run Photo AI on a non-RAW image. And in the noise reduction I get the line to Recover Original Detail.

I’ve tried moving the slider around and don’t normally see much of anything happening unless I push it to 100. Then I see some noise come back… Is there any relationship between the Strength value and the Recover Original detail? So if Strength is 50, Recover is good at around 25? Or 50? Or 100?

Is there something I should be looking for when pushing the Recover slider back and forth?
