Rob--

I've told why I claim that FBC is essential for a political voting system, 
and that MDDA meets FBC but BeatpathWinner fails FBC.

I've just told why SFC is better than Condorcet's Criterion. Sure, for 
sincere-voting committees and organizations, which don't really need FBC as 
badly, I prefer BeatpathWinner to MDDA, because, though MDDA meets SFC and 
SDSC, BeatpathWinner additionally meets GSFC, Condorcet's Criterion, and the 
Smith Criterion.

But SFC compliance really brings the best of what BeatpathWinner offers. And 
that can be gotten in combination with FBC, when MDDA is used in public 
elections.

Say there are some sincere voters, as you say there will be. None of us can 
say what percentage they'll be. But, with MDDA, they have SFC's guarantee. 
In other words, those sincere voters aren't giving up much with MDDA, since 
SFC is better than Condorcet's Criterion.
