Use ISO 100 and expose to the right. You lose 1 stop of highlight recovery vs ISO 200 but you gain ~1 stop back in shadows (this is common for call cameras doing this underexpose, re-develop back up trick).

The above is simply not correct. You do not gain anything in shadows by using ISO 100. The native ISO for the DPM's and SD1 is ISO200 where you get the most dynamic range, period.
ISO 100 does have less noise than ISO 200 no? What do you think that means?

ISO 50 has less noise than ISO 100, what do "you" think that means? The dynamic range of the sensor has been measured and is best at ISO 200, period. All your arguments to the contrary go against the real world experience of numerous photographers who use the camera daily and professional review sites who "measure" the dynamic range.
Do you mean like dpreview? Read what they say about the SD1 dynamic range. It isn't that much different from what I said. But it doesn't really matter. The camera does have an ISO 100 setting. What I see is a lot of people thinking that highlight DR= total DR. Both have to be taken into account.
By overexposing ISO 200 to protect shadows, you effectively cut off the "great highlight DR" you are seeing at ISO 200.
So who do we believe? Those who have real experience or the arm chair expert who takes photography lessons?
Those who have real experience, which btw, also includes me
But the best to believe is reach respective person. I proposed what can be done to check it out. You don't have to believe me and find out for yourself. That is the best.
If we have the spirit of actually listening, you could just try what I suggested and see for yourself. You don't have to believe me. You could go in and do this with the hypothesis that I am still wrong.
