all the final-round support for the IRV winner.<br>

If the IRV winner will be considered below all cutoffs, it looks like we want the IRV<br>
winner to be defeated if at all possible. That doesn't sound good from a monotonicity<br>
standpoint.<br>

That said, I'm not seeing how the two rules give a different treatment of the "Z>X>..."<br>
ballot in that scenario, where X was the IRV winner and Z was the other finalist.<br>
