A chart of estimated values.

Wrong. All of them are *measured* values. Read the details and
don't take words out of context to change their meaning.

Regardless, DXOmark.com now also has evaluate both the D4 and
the D800, and Bill Claff's data is confirmed.

A chart based upon images taken from the web.

Eh? What difference is that supposed to make?

I'm confident DXOMark will confirm the above in their own tests.

There is nothing to certify. There is guesswork.

Well lets, see... in addition to those three, Marianne Oelund
has published similar data. So there are multiple source all
showing similar results, leaving no wiggle room for arguement.

Color me unimpressed.

So?
