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.
