Two questions:

(1) what methods actually meet strong FBC?

It seems to me that ERBucklin(whole), which is what I mean by "Bucklin",  
meets Strong FBC.

The Approval Elimination IRV proposed by Kevin is likely to have some or 
many of Bucklin's good properties. I haven't thoroughly checked it out yet, 
but it could turn out to meet Strong FBC too, maybe with AERLO, or maybe 
even not needing AERLO. Approval Elimination IRV seems promising, though I 
haven't checked it out yet, and so I make no claims about it.

Almost surely Approval Elimination IRV's merit is somewhere between those of 
Approval and Condorcet wv.

You continued:

(2) Assuming ERBucklin means Bucklin where equal-ranking is allowed, why
the "Equal" part?  If it meets strong FBC, why would anyone want to
equal-rank?

Ok, so that's three questions.

I reply:

They seem to me like just 2 questions, one of which uses 2 sentences.

The method itself, before adding AERLO, allows equal ranking, and that 
allows AERLO to do automatic equal ranking. The fact that AERLO does the 
equal ranking means that the voter doesn't have to, to accomplish Strong 
FBC's requirement.

The voter isn't insincerely voting anyone equal. Hir sincere voting of X 
over Y could make X beat Y, even though AERLO can promote Y to 1st place 
with X if needed.
