Yes, you're essentially right. There is a map for each of the members of the ERRE. Wilf is the one who did all of these maps. That is why I was frantically pointing to Wilf over here.
You're supposed to have one map for MMP in each case, and one map for rural-urban in each case. Rural/urban also illustrates what the STV might look like because under rural/urban you might be using STV as your multi-member mechanism.
