Yes, the current poll is about single-member systems.

On your other point: while CPO-STV *is* an elimination method, Schulze 
STV is not. Schulze STV works by comparing outcomes (ways to elect the 
required number of winners) that differ by one candidate. It then 
generalizes the Schulze method to find the best outcome based on these 
comparisons. I'm not quite sure how the comparison function works: it 
uses linear optimization. But there's no sequential elimination of 
candidates.

I'm not saying that the poll is about unified methods, just that if 
(say) Schulze wins the poll, then that doesn't immediately preclude one 
from considering multi-winner methods since anybody who thinks Schulze 
is the best single-winner method could view it as just a special case of 
Schulze STV.

I don't know what that means, unfortunately. You're using terminology 
that I don't understand.
