Paul, without hijacking the thread, let me just interject that the only inks we really absolutely know are 100% carbon are those we know you mix yourself, and the older Carbon Sepia Piezotones, based on statements by Jon and Bill Bergh. I don't recall a similar statement made for the K6-7 Sepia Cone set, and there have been explanations of the K7 sets about going to great lengths to hue match each density, not merely dilute, via some method, including the sepia version.
Perhaps it's rhetorical, but I think we are making assumptions about the make up of various ink sets based on the testing results. 
That's logical to be sure, but I think if there is more going on with all of this than is obvious. The HP inks are testing well, and I seem to recall they are not 100% carbon.
Hence my statement that the 100% carbon ink print may be an illusive beast.. it's just not all adding up neatly in my pea brain.
