No. I just meant MJ, with all voters voting approval-style (max or min for
all candidates).

And I just explained the tiebreaker in that popular proposal, as put forth
in the book Majority Judgment. You apparently had never even heard of that
tiebreaker, so I don't see why you think you're qualified to say anything
about MJ.

I could continue to point out how you're wrong in what follows. For
instance, you apparently think that "probabilistic SFR" means everyone
gives the higher grade. But it's basically a waste of time.

As a wise man once said: "The EM conduct-guidelines ask you to not repeat
claims that have been answered and criticized, unless you can answer the
criticisms of the claims." Until you understand that guideline, rather than
just parroting it, this is the last time I'll respond to you in this thread.
