Digital BW, The Print

I totally keep forgetting to ask two things that I've wondered about for a long time,then I'll let this thread drop and get back to work.



1. Does anyone have any link to concrete scientific fade tests of well processed and washed gelatin silver fiber print material (BW)? It seems like I remember RIT publishing data on silver prints many years ago. What kind of conservation rating would be applied to gs prints?



2. What about "dark storage" of type C materials like Fuji Chrystal Archive? I remember Wilhelm writing about how well Cibachrome held up in dark storage (hundreds of years) while C prints did not perform nearly as well. So I'm wondering how I Metric relates to dark storage of C prints in average temp and humidity. 

I know one thing all the Kodak C prints I did 20 years ago are all mostly red now, not showable, and were stored in decent conditions, but certainly not cold, dry storage like a museum vault. Friends and colleagues of mine have all experienced the same degradation. But these were all Kodak C prints. I wonder how much the lack of good thorough washing from  commercial print processors (probably contaminated as hell with bleach fix on the rollers) added to this.
