Are we talking about intentional or unintentional inaccuracies? Unintentional ones should be distributed more or less evenly, if everyone have 10 less votes it should not change the end result. But intentional ones, with the objective of trying to rig the result in one particular direction, and deep enough into whoever is doing the count/election. But in the end, it goes to how big the conspiracy should be? You may need just a few to rig all the voting machines (do you have the source code? of what was actually running in production everywhere?), but with human counters to get to the right scale you may need to involve really a lot of people.
