Uh-oh, Bus doesn’t defeat BF. But Bus can’t be defeated.

…& so wins unless someone else is un-majority-beaten due to lots of
truncation.

I guess Bus could eliminate CW before BF meets CW. …& CW was BF’s only
defeater.

But BF might be eliminated, & Bus can’t be eliminated (because hir only
top-cycle defeat isn’t helped by the defensively-truncating CW-voters.  …&
Bus, as a top-cycle member, has no defeats from outside the top-cycle).

So, probabilistic-deterrence.

SP, only counting majority-defeats.

It never elects BF*, but it might well elect Bus.

*or so it seems to me.  …so: unless I’m mistaken. BF has a majority
defeat. Bus doesn’t
& therefore can’t be eliminated before defeating BF.

It brings wv advantages to easy handcount.

It doesn’t even matter what the agenda-order is, but, as you said, IA
would be good.
