S: Please correct me if
I have misunderstood you to mean the following:  The more reps to be
elected from a multi-winner district (from many more candidates) by
an electorate of many millions of citizens, the probability of
monotonicity failures (and thus 'unfairness') would becomes almost
fanishingly small.  




If so, this would be
the case with APR because its general election, in effect, elects all
reps from one district (i.e. the whole country, even though it is
initially administer through all the single-member district in the
country).  Moreover, the probability of monotonicty failures
occurring with APR is made even smaller by its giving 'weighted
votes' to each rep in the assembly, i.e. the transferring of
so-called 'surplus votes' is not a part of APR's modified use of STV.



What do you think?



Steve
