For some, this might not make any differnce at all. Others, even one nano single spot of damage on the film negative is completely unacceptable.
Personally, one liter of plain fixer goes for about 10-15 roll of 120 film or about 20 to 30 sheets of 5x7 film or two to three months at most. Once past these limits, the fixer is re-newed. No exceptions.
There is simply too much effort and resources put into film images that the "pennies" that might be saved by over extended fixer..
It is possible for those new to this film stuff, none of this is important or significant.. as there are folks new to film that seek making film images for randon imperfections as a idea of creative expression.
