Just to recap.

I chose SNR = 20 which ISO says is "good" (They also say SNR = 40 is "excellent" )
ISO also says SNR = 10 is "acceptable"
As I understand it, SNR = 5 is considered the limit of usable feature detection.

Just out of curiosity, are you saying that the "International Standards Organization" ("ISO") has deemed this or that image SNR as "acceptable" ?

Yes, ISO 12232
