Your certainty inspires resistance:

Those of us who bullet voted for Z could prefer Y over X, and thus surprise 
you.

Still, X has good odds.

BTW, I would not do runoffs with Condorcet, even with cycles - promise of 
no runoffs can encourage more careful preparation for the primary vote 
where Condorcet allows complete ranking.

            Do to no one what you would not want done to you.
                  If you want peace, work for justice.
