While I'm a skeptic about all these RC type papers, I think Wilhelm is 
doing some accelerated age testing.  This is what gets reported in 
the "Album/Dark storage" category, and he rate Premium Luster as ">300 
years."  Personally, I'd stick with buffered cotton for longevity.  
Accelerated age testing is not that good at its best.
