All that matters is whether it's possible to verify whether this insecurity affected the result, based only on the precinct results. RCV is round-by-round verifiable: in each round,ONLY if tallies for all operationally distinguishable ballot permutations are posted at each polling place after closing on the evening of the election.That's 9 tallies for 3 candidates.  40 tallies for 4 candidates.  205 tallies for 5 candidates."Combined Write-in" is one of those candidates.The closed-form formula is# of tallies = floor( (e-1) C! - 1)where C is the number 
 of candidates.Of course with most Condorcet, it's C(C-1).Big difference in the length of paper tape.> you can post the vote totals for that round,Only from the central tabulation location.  By then the conspiracy theorists would say the numbers are contaminated.> and verify the outcome was correctly calculated by adding up all the precinct results.Again, you need 2 meters of paper tape if there are 5 candidates.
