It is a very nice algorithm, which does about as well as any
polynomial-time algorithm could using rank ballots. It certainly
overcomes a lot of the practical pathologies in ScottishSTV or more
generally IRV-based STV systems.

I would agree that, assuming rank ballots, Schulze STV is the most
sensible choice.

If I were ranking them as fit-for-purpose in the current context, I'd rank

  RRV > Schulze STV > ScottishSTV > Current System

If I wanted to be more informative, while using the entire dynamic
range, I'd say

  RRV: 99
  Schulze STV: 90
  ScottishSTV: 50
  Current System: 0

One issue with Schulze STV is that it is hard to explain to people who
are not mathematically sophisticated. That should not be a problem
here.

Cheers,
