It's worth reading this article on the RAWDigger site particularly this conclusion and the reasoning behind it for the Canon 5DII they used as an example:- "ISO 50 is the same thing as ISO 100 with an overexposure of 1 stop. There is no point in this ISO setting."

Yes, but on DxOmark the 5DII 50 and 100 setting produce identical results, the Rx100 80 and 100 ISO settings don't, yet Amin gets identical results, that is what is puzzling him.

Experimental methodology, measurement error and scatter - 80 and 100 are only 1/3rd stop apart, probably need to repeat the measurements separately a few times and average out the results discarding the outliers.  I would tend to believe Amin's results as it ties with other cameras (including my D700s ISO100 setting) and DPReviews results.
