Hi,
I'd like to understand if STeVe uses the Weighted Inclusive Gregory Method
(WIGM) which is described as best I can below. It seems to be the most popular
of the public election methods.
I understand that other methods are also in use: Meek's Method and Warren's
Method. These are described in more detail at
https://en.wikipedia.org/wiki/Counting_single_transferable_votes
Can anyone confirm, or tell me which method is used by STeVe?
We have always used Meek's.

Multi-winner races here. I think this is what surplus transfer means:
When a candidate has more votes than needed to win, the extra votes are
distributed to the voters' second/third/etc choices.
But which voters' ballots are looked at for their next choice?
Seems like all voters who voted for the winner should have their next choices
counted, and a proportion of those votes should be distributed.
Example: Candidate A wins 50 votes when only 30 are needed to win. So 20 votes
should go to the 50 voters' next choice. Of the 50, 15 voters chose B, 17 chose
C, and 18 chose D. There are 20 excess votes to be distributed.
So
15 * 20/50 go to B
17 * 20/50 go to C and
18 * 20/50 go to D.
Is this the way it works?
