ASM could be modified to work with an odd number of slots.

Preferred ranks A and B would get 2 points.

Acceptable rank C would get 1 point.

Compromise ranks D and F would get zero points. Additionally, rank F, as
the lowest rank, would get no pairwise votes over any other rank.

Seed the initial ordering by total points and then proceed with sorted
margins based on points.

This could be adapted to any odd number of slots.
