I must admit to also having heard/read somewhere that for FB paper a "film" dilution of 1+4 was better on the same basis as Alex has said, namely that the two dilutions do the same job but as 1+4 does it more quickly there is less fixer penetration to wash out. On the other hand if fixer has to penetrate to a certain level and in a set quantity to do its job which is time related then is less fixer for longer in fact any better than more fixer for less time if the minimum amount needed is strength and time related?

I confess to not knowing enough about chemistry of paper processing to know.
