Re: [OVC-discuss] Ranked Choice Math

I don't understand the claim of impracticality. The system is
essentially ranked choice without all of the rules, and Australia
seems to have no trouble at all putting incredible numbers of choices
on their ranked choice ballots. Over vote? we'll take the highest.
Undervote? we'll assume don't care and you won't impact the average,
or that you don't care and give the candidate a 0. Don't worry about
any of the other names on the ballot, just rate the candidate by how
much you like them, just like you rate things on amazon, rotten
tomatoes, or any other website that asks you to rate products.

RV is a system of minimal thought. There are no dependent choices, all
you are considering is that candidate for that race. You don't have to
just choose one, keeping in mind the other important candidates in
order to decide on which one is best. You don't have to keep track of
your previous rankings. There are no lame rules that would invalidate
your ballot. All possible spots to mark on the ballot are legitimate.
The counting is also relatively straightforward -- add up all the
numbers, or do piles based on range for each candidate.

I'd say 0-9 or 0-10 is probably the best range, because it is what
most people are familiar with. Others say range should be # of
candidates, so that people have the ability to rank if they so choose.
CRV really hasn't asked or answered the question of what range is the
best range. I'm not sure anyone over there cares.
