Re Party List vs. nonpartisan PR, the difference there is the number of winners, not the partisanship.
Granted but if you partisan vote then the same ballot works for any number of winners. Parliaments are typically over 100 seats. You are never going to run a ballot with candidates for so many seats. So what I am saying is true in practice but not necessarily in theory.
I have no idea where exactly STAR or Cumulative should go, or which order they would go in. I'd like to think they should be reversed, but I also have no basis for that.
I do not have the time to write simulation code. If only there were universities who would sponsor people to study this.
