Reply #1: Can anyone explain how punch card tabulators work?

[roseBudd]

As old technology it seems to have escaped scrutiny, probably because the punch card themselves are evidence. As of yet the punch card evidence has not been examinesd so the perps may have thought it safe to meddle with the tabulation.

According to Dr. Doug Jones:

We can now formulate the basic counting categories that must be reported at every level in the count, from the precinct up to the highest level election authority.

At each level, the following totals must be reported:
a: ballots distributed
b: ballots rejected (including spoiled ballots)
c: ballots challenged
d: ballots voted
e: ballots unaccounted for

At any point a = b+c+d+e.

On receipt of a report, if this condition is not met, the report should be rejected.
On receipt of these numbers from a lower level in the hierarchy, the sum of the final four ballot counts should equal the number of ballots distributed. If this condition is not met, the counters at the lower level in the hierarchy have made an accounting mistake and should search for the source of their error.
