Until, that is, a few days have gone by after the vote and the RATs (now knowing how many they need, and how many voters failed to show up at the polls) "find" more boxes of paper ballots that were "misplaced". When that happened in the past, did anyone compare the tally of physical voters with the number of total ballots? I think not!
If you want to get right down to it, there is always a way to cheat. What I am proposing is a continuous roll of paper in each machine where the number of ballots totals the number of people who have voted on it. It also tallies the number of “no votes” when the voters votes for no one.
