Do you consider Paul Roark's testing as 'internal'?

Does anyone have reliable info on the true permanence o UT7 
pigment inkset by MIS? I mean by someone who is a scientist 
who doesn't sell their products. I realize becaue of the quality of 
the tonal rendering and the price difference with Cone's new 
inks, it may not bit a big issue with a whole lof of people, 
possibly no issue at all for a lot of you.

But for me I still need reliable confirmation in order to sell work 
for exhibitions and galleries, etc. I know from past experience 
there is a lot of misinformation out there from Cone's early 
proclamtions of "carbon pigment the oldest substance known to 
mankind" when they later addmitted to me they were realisticly 
rated at 50 years in average daylight .. to the Lyson propaganda 
that their hextone inks would "outlast most gelatin silver prints" - 
and their archival inksets were rated about 75 years at the very 
best without spraying them. 

So, why does't MIS hire a reputable testing facility or two? 
Please don't tell me it cost too much. This is their responsibility 
and it has to be factored in.

Bottom line is why should anyone trust their internal tests? In 
terms of years, what DOES their internal testing data reveal? 
And, yes equiveliency in years of permance does matter to my 
clients.
