I tried to carefully follow your instructions on this page. My middle grey is roughly similar to yours at 1675 but my G max is only just under 4096. 4096 is the maximum theoretical value for 12 bits. Your example for a Nikon used a 14 bit raw file. So my EV distance between midle grey and max is only 1.27. That does not seem reasonable. I tried looking at the same sample raw files with a number of other programs, even FastRawViewer and they show that I have at least 3.3 stops between middle grey and blown.
My determination of the maximum values works exactly as you describe, including the Standard Deviation. When it goes to maximum, 4096 is as far as it gets.
I am a new user of RawDigger and I've had FRV for more than a year (I love it).
If I am missing something, I'd appreciate some guidance.
