Do you mean multi-winner elections?  (Even so, it might be a disputed notion.)

In my opinion, William Ware's contribution to the thing is virtually a "nothing burger".  It is Thomas Hare who is credited with the idea of the Single Transferrable Vote and that is the key innovation that was used to convince policy makers that were was no multiplication of votes and made the method feasible.

That makes pretty much no sense to me.  The ballots are **purely** ordinal and that ballot information is not lost in Condorcet.  But for each individual pairing, there are only two rankings that mean anything.

What information is lost?  Because I can certainly point to how information is obscured with Hare RCV that results in the Center Squeeze (which is the root flaw that broke the Burlington 2009 election).

I don't see a completion method at all mentioned in the article.  The author's define "an electoral system called true majority rule (or simple majority rule), in which voters submit rankings of all the candidates and the winner is the one who beats each opponent in head-to-head competition based on these rankings."

It's just straight-ahead Condorcet.
