[EM] IRV Finisher DSV

I suppose you would offer it to an audience that already thinks the IRV winner has merit (and is worth the
trouble of finding) yet is sympathetic to the idea that IRV gets it wrong sometimes and could use a patch.
So this proposes what sort of situation might be so egregious that it calls for a patch.

So if the Condorcet Winner is neither X nor Y, why is the pairwise choice between the IRV and Approval winners a "good thing"?

It is an interesting idea but I think it would be more fair if it were like:

IRV winner X, approval winner Y where X is (exclusive) cutoff on all ballots, then pairwise of X and Y wins

Otherwise, what if the final round of IRV is X and Z, but my preferences happen to be Z > X > (everything else), seems like my vote would be mostly ignored.
