[EM] STV is suppose to be a PR method.

Wasted Votes & Hare STV

STV is just the STV method isn't it.
It is not all that proportional. The lower the 'quota for winners', the
 more proportional STV would be(?). Droop-STV has a smaller quota for
 winners than Hare-STV, so it is more proportional (is there an error here?).
 Previously the test was 'vote wastage', which is different (isn't it?).

That is the first use of the word "policy". How did you get to the idea,
 "policy"?. What is the "policy"?. What is the definition of a "belief".
Policies are something that can be photocopied or else (or else there
 might be an Information Ombusdman investigation).

This is similar, but vote wasting has been replaced with proportionality.
The two are not the same and neither are defined. If you have in mind some
 little sample elections that test methods' proportionality then perhaps
 you could give them.

I'll repeat this, and it wasn't replied to.

(1) 'Hare' : (A B C D E F G H I J K L M), Winner = {E,G,L,M}, Satisf.=323/8192
(2) 'Droop': (A B C D E F G H I J K L M), Winner = {C,D,E,L}, Satisf.=897/4096

In this example, Hare-STV gets an extra winner at the very end, but it
 became insensitive to the voter intent in the middle.

What has PR got to do with STV?.

People don't believe that Droop is more tailored for their corruption, yet.

The message that seemed to be at the start this topic, was one that
 referred to Meek-STV: "Meek style STV - Part One of Two", 13-14 October
 1999. I note that that message indicated that Mr Stephen Todd (Electoral
 Reform Society (UK)) was using a computer program. I reproduce part of
 that message:

Can Mr Davison use a program too, and prove Hare-STV is better?.
(Random numbers)

I have a question to and for, Donald Davison:

      How much better is Hare than Droop? (exactly, how much better?)

Suppose the virtue (with respect to vote wasting) is: d, h, t for
 Droop-STV, Hare-STV, and FPTP respectively.

What is d/t and h/t?.

Make the number of winners and losers may range from 1 to 20, and take
 quite integral values.

Since a method that minimizes vote wastage may not be one that maximizes
 proportionality, how do you define both those?, etc.

What obstacles would you have in numerically resolving the question:
 Does Hare-STV waste less votes that Droop-STV?.
