So I take it you are assuming a zero-info situation.  Just about any other
situation would require that A be predicted to have some chance of winning,
which doesn't seem very realistic.

IIRC my simulations did find that as the number of candidates increased,
zero-info Approval did worse in comparison to Schulze.  With five candidates
it was a little bit better than Schulze.

I consider myself possibly a "fanatical advocate of Approval," but I don't
feel that SU performance is an important argument for it.
