So the net of this conversation is that DxO Analyzer is flawed in that it doesn't mimic what might be realistic if someone used an actual raw converter.

Or that it's definition of DR is not precisely what a photographer would consider useful DR. Or it's possible that Thom was using RawDigger's analysis of A7 raw files which may define DR using different quality thresholds than DxO.

I will go so far as to say that Thom believes that based on his experience with the carmeras and ACR, that ISO 200 is the optimal ISO.

Given so many potential variables (of which DR is only one), "optimal" is inherently subjective. It would be useful if Thom elaborated why he thinks ISO 200 is optimal.
