This has to be stressed over and over. All you have to do is go through the results, and see the differences between the various high end fine art papers with the same ink sets. Some consistencies take shape, and the major difference has to be brand coating chemistry differences.
Even though it is currently scoring fairly well, but inconsistently, this is one reason I wish HPR was NOT the paper we use to look for inkset performance differences.  As a printer for others, I have had a lot of HPR go though my studio since it's introduction into the market. It is the most problematic paper I have ever worked with in terms of consistency, paper base hue and whiteness, dmax, ink load capability, etc... In addition, the yellowing associated with the visible creation of some sulfur compound in reaction to the coating and certain airborne chemicals seems much more common with HPR than other papers.
This has nothing to do with Mark, he tests what's submitted. Also, I don't mean to disparage the HPR information so far, not at all. It's scoring well with various setups, but it makes me nervous...
It will be interesting to start to see some of the uncoated results start to come in as well.
I hope Aardenberg finds enough support to stay healthy over time, as the more data we have to compare, from more combinations and time, the more useful the database becomes.
I can think of so many combinations to try...
