Are you tray processing? Closed tanks like Jobo or such? Other method?
Knowing the minimum needed is fine but no room for variables if you stick to that volume. Better to have some extra than right at the minimum, even with 'fudge factor' in mixing.
Mixing One Shot developer will give you more consistent and repeatable results than re-using developer that has lost a bit of its action. The cost of film and the time involved in photographing is more valuable to many of us than the cost of a few ounces of developer.
Good luck.

Why would anyone develop unexposed film, Pere? You might want to re-phrase that.
Drew, IMHO one can extend developer capacity beyond manufacturer's recommendations, but one has to be aware of the risks, in special if recommending other people to extend capacity.
Developer exhaustion depends on the amount of silver developed in a negative, if developing very dense negatives then a developer amount can develop less sheets than if the negatives are very thin, ideally if the sheet is not exposed then developer the exhaustion is very low, but if negative it's very, very dense then the actual capacity gets closer to the one recommended by manufacturer.
This has to be warned when recommending extended developer usage.
