The problem with that analysis is whether or not the noise is correlated.
SBIG have sublime temperature regulation (1/100th of a degree)....better than most....hence you can ramp up the gain and get a tad more signal and, yes, you get snow, *but* when reduced the data has bugger-all correlated noise.
I have stacked thousands of frames with SBIG gear and have yet to see a correlated noise pattern build.
