[EM] Question for STV-PR supporters

[Alex Small]

I have an honest question for people who think that STV-PR and related
methods are the best way to implement proportional representation in
public elections.  I'm not trying to be combative, I'm just curious.

How many members should a typical legislative district elect?  I doubt
anybody would seriously propose using STV to elect representatives for,
say, a 50-member district, since the number of candidates might be a few
hundred.  Obviously voters wouldn't have to rank all 300 candidates or
whatever, but the ballot would still be pretty imposing.

So what district size would you recommend?  Or, what is the typical
district size in places that use STV-PR for public elections?

Note:  I'm not in the same camp as Approval supporters who say "Voters
don't want to/aren't well-informed enough to rank all of the candidates"
when the number is, say, 10.  But I personally would have a hard time
ranking 100 candidates, and I'm pretty sure most other people would too.
