That's very well written, Mark.
I guess what I'm trying to say is that if Xtol is given 6-12 months as 'life span' by Kodak after it's mixed, and if properly stored, I'm getting 100%, because after 6-12 months in accordion bottles I see no difference.
So it raises the question of what level of importance should be given to storing your liquid concentrates and working solutions in vessels that have better characteristics than accordion bottles.
I don't like 'convention' and assumptions. I like to see for myself by doing. Empirical evidence outweighs theory, in my opinion.
