A rounding error on the release date isn't the most sensitive mistake if inmates have already done most of their time (and crime relapse is only probable because prison and reinsertion programs aren't working). Scheduling cells and inmates, tracking security cards, tracking prison risks are much more risky, they can lead to a revolt, guard assasination, etc.
