Well, I hope the working solution keeps for at least a month or even better 2. I will be mixing 750ml as well (easiest size of bottle to find) and that's good for 15-21 rolls of film.

Maybe even more, since it's going to be in Japan and film is quite cheap over there.
Also since I'm going to get some iso800 film, I can extrapolate that the solution is only good for around 90 x iso800 rolls? Might be even less if I push it.
