FYI,
After discussions today with the SF group of activists, I realized
that my prior fla in my IRV paper for the number of vote counts which
must be publicly reported in each precinct prior to randomly selecting
precincts to manually audited (corresponding to the number of possible
permutations of candidate orderings voters could select, assumes that
voters are allowed to rank from one up to all N candidates.
If voters are only allowed to rank say up to 3 candidates, as in the
SF IRV elections, then the formula changes to:
given:
R = the number of possible rankings or IRV rounds
N = the number of candidates in each election contest
the total number of permutations and the number of vote counts which
must be publicly reported for EACH auditable unit is (drum roll):
the sum from i = 0 to i = R-1 of N!/(i+N-R)!
That gives for San Francisco elections:
for 2 candidates, 15 vote counts need to be publicly reported for each
IRV election contest for EACH precinct prior to randomly selecting
precincts for auditing
for 9 candidates, 585 vote counts need to be publicly reported for
each IRV election contest for EACH precinct prior to randomly
selecting precincts for auditing
Not that IRV proponents seem to care about checking if the machine
vote counts are accurate or not, but when there are fairer voting
methods that actually solve the spoiler problem in all cases rather
than in just one case, and are far easier to manually audit and count,
the people who support IRV should think twice about whether any gains
are worth all the expense and effort of IRV counting methods or not.
