in the real world it's usually not worth achieving a literal 0% of something when 0.01% works fine. foods often contain trace amounts of poisons, heavy metals, etc. the amount of effort required to ensure that absolute 0 makes it in is not worth it. nobody has ever provided any solid evidence of widespread fraud that actually affected the outcome of the 2020 presidential election in the us. also, for the millionth time - this particular rule does nothing to prevent cheating. the date is not validated in any way - if you wanted to fake ballots all you have to do is put the correct fake date in the spot.
