Given the
rougher-than-average schedule 2815 drew at Palmetto, I would be leery of being stuck for an entire tournament with one alliance, no matter how many well-planned algorithms tried to ensure parity.
(Plus, I won't lie, I was bummed that we didn't get to see 1902 amongst others at all in qualifying. We wound up meeting in semifinals, but there were far too many variables to guarantee that in advance.)
