I do know that about IRV and that the Hare threshold was too high for single-winner. The thing that I think is the defining idea was the notion of the Single Transferable Vote and the elimination of the bottom candidate each round. It seems to me that the basic mechanism is essentially the same whether you stop at a single winner or earlier with more than one.
Wikipedia tells me that it wasn't Hare but Thomas Wright Hill that was the first to propose the STV. And I know that Ware is credited specifically for the proposal to use STV for a single-winner race. But it seems like this was all he contributed and I just think it's historically better to ascribe the STV idea to Hare or, now I read, Hill.
