Preference matrix

There are 56 possible sets of 3 choices that can be formed by selecting from the 8 choices. Of these, 4 sets were considered thoroughly, comparing against the 16 nearby (similar) sets that differ in just one choice.

This is the voting preference matrix, reporting maximal valid proportional preferences. Fractional digits indicate nonproportional preferences, which help break ties in proportional preference.
