How summable or not is an IRV election? In pathological theory, it's bad. There are over factorial the number of choices possible rankings votes.
In that Burlington data, I counted 9866 votes but only 562 unique rank arrangements. VRR/Condorcet would still only require 30 data points to sum up intermediate results for 6 choices. Take that data point for what you will. If we assume computer calculation it doesn't matter. One representation of the total vote set is 446082 bytes uncompressed and 10353 bytes after bzip2.
