IRV is of interest ONLY to those considering using that - hopefully no
one.
Condorcet would be of interest. If ballot format permitted assigning
multiple ranks to any candidate, educating its voters as to this
problem would be of interest. Otherwise, how could Condorcet be
expected to have more trouble than Range?

simpler rules?
--range is of course not immune to spoiled ballots, but it seems to do
better than
rank-order ballots (IRV, specifically) and (and this part is
surprising) plurality voting,
at reducing spoilage.
But range is not better than approval voting at reducing spoilage &
voter errors.

although this page could use some updating (it refers to various new
data,
which you can examine via hyperlink, but ought to be updated to
incorporate that
data directly; if you edit this page's plaintext source to do that &
email result to me that'll happen)
