As for test results on different papers, well, they fix at different rates and wash at different rates. RC washes far faster than FB paper.
Archival fixing/washing was a lot harder to achieve with acidic Sodium Thiosulfate based fixers and has gotten a lot faster and easier with modern near neutral rapid fixers. What Raphael considers a "quick wash" might indeed be archival for certain fixer/paper combos.
Trying to be the best of whatever I am, even if what I am is no good.
