Let me make this simple by working though it...
The 5D2/5D3 are almost identical in terms of measurable DR.
Measured by what method?
Why don't you write an email or letter to Chuck and ask him how he measured the DR of the 5D3 and 5Ds in order to make the statement that he did? Come back and let us know what he replies with.
He, Chuck Westfall, didn't measure anything. Canon told him to say exactly what he said, and that was "Canon is telling us......equivalent to the 5D MkIII" They also told Mike Burnhill to say exactly the same thing, and he did. I am sure every senior Canon tech around the world was told to use the same expression.
Well then why don't you ask Chuck to find out how Canon came to that conclusion?
There are two possibilities here:
(1) Canon measured the capabilities of the 5Ds/5D3 and came to the conclusion that is being mentioned by Chuck and others;
(2) Canon measured the capabilities of the 5Ds/R, have not told Chuck and others the truth and told them to spin a story that effectively means Canon is currently lying about the capabilities of the 5Ds/R.
