If you trade Approval for ERIRV with AERLO, you're trading FBC for SDSC. If the choice were only between Approval and ERIRV with AERLO, I'd probablly choose ERIRV with AERLO, unless that od's FBC violation turned out to be frequent and flagrant.
This is in answer to the question about how ERIRV rartes with respect to other melthods.
Just tentatively, a merit ranking of ods might start something like this:
1. Condorcet wv 2. ERBucklin(whole) with AERLO 3. ERBucklin(whole) 4. Bucklin without ER 5. Majority Choice Approval 6.. ERIRV(whole) with AERLO 7. ERIRV(fractional) with AERLO 8. Approval or CR 9. ERIRV(whole) without AERLO 10. ERIRV(fractional) without AERLO
[then probably lots of other ods]
then Condorcet (margins) [ranked this low because it doesn't even meet WDSC] then unmitigated IRV, the IRV proposed by IRV promotgers then Plurality & Borda (difficult to choose between those two)
But, again, this is about merit. The popular public proposals are Condorcet, Approval, CR, unmitigated IRV, and maybe Borda, which would make for a shorter, simpler ranking:
1. Condorcet wv 2. Approval or CR 3. unmitigated IRV 4. Condorcet(margins) 5. Borda and Plurality
Polls have been suggested for ods, and for criteria. I suggest that the next poll, when the presidential poll is completed, be about standards for voting systems. Then a poll for criteria to measure for the winning standard. Then for ods that do well by the winning criteria.
James A.-- If you agree that Condorcet is the best rank od, then there's no need to propose any other rank od for public elections, since computer-counting is available for public elections, and so the quick handcount of Bucklin & ERIRV aren't needed.
And if you prefer ERIRV to Bucklin, why is that? LNH?
When I say "Bucklin", I mean ERBucklin(whole).
