But it's already been demonstrated that whether there is one
vote or more per seat is just a matter of definition.  If a
perceived problem turns out to be a trivial technicality that
depends on an arbitrary definition, why should matter?

What is so special about the number of marks on the paper?
Why is one vote/seat a good rule?  Yes, I understand that it
reminds us of what we have now, but if that's what counts,
the best thing we could do is use Plurality, which is as
close as we can get to what we have now.
