I've added a subject because "(no subject)" is not acceptable.

Steve, you need to improve the above wording, both to allow us to give
you feedback, and because an unambiguous wording will be needed to enact
your actual intended method (and not end up with what someone else
changes the wording to become):

Here are some ambiguous concepts:

* Using the word "proxy" without saying what it means in this context.
As a guess, if your method gives unequal voting weight to the elected
council members, that needs to be explicitly stated.

* The words "graded that candidate highly" are unclear regarding HOW highly.

* The words "not enough" aren't specific.

* The words "contains no such remaining highest graded candidate" are
unclear.

* Not explaining what happens when two or more candidates are rated at
the same preference level. This might need to be a separate paragraph.

I agree there's a need for a multi-winner STV-like method that uses
rated ballots, and is better than STV.

But without being able to understand your words it's not possible to
know whether your method meets that need.

As always, I'm offering my opinion, and others might disagree.
