Sigh.  Yes it deters truncation, but now I have to randomly fill out my 
ballot so that the other front-runner can be in last place.  If I don't do 
this I'm giving the election away.  Hopefully one of the two gets a majority
before some turkey does...

I think you might consider implementing QLTD (Quota-Limited Trickle-Down)
which is a Bucklin variant suggested by Woodall.  One would modify the
last sentence in your definition to become:

> Elect the candidate requiring the smallest percentage of his latest-round 
> votes to reach a tally of half of the votes (or a majority).

Looking for the smallest required percentage simulates greater ballot
resolution than actually exists.  You can pretend there was a 2.203th round,
for instance.
