I don’t understand how SPAV fixes gerrymandering in this case. It seems like the re-weighting operation is meant for a pool of identical ballots. When you have district-level elections that differ between ballots, how is this meant to work?
Edit: Ooooh you meant for selecting the redistricting committee, not for running the elections. Gotcha, makes sense now.
Okay, that makes a lot of sense. Thanks for explaining it further. It does sound like a very nice system.
