Panasonic S1R: Signal/Noise ratio for Multi-Shot vs Single Shot, ISO 50 to ISO 1600

In Panasonic S1R: True ISO 50, not a Faux ISO — Kudos to Panasonic, I discussed noise and and the signal/noise ratio derived from images I had taken from ISO 50 to ISO 51200 in 1/3 stops (RawDigger folks analyzed the images). That series was not ideal (and not shot for) the purpose of showing the true S/N ratio because it was shot in-focus, which means that standard deviation calculated on the gray patch is increased by subject detail, including dust. So while that graph is valid relatively speaking for each ISO and the patterns it shows, the signal/noise ratio is lower than it otherwise would be.
