For results among subsets of entries (all levels from a given design-rule), seriously consider ditching polls, in favor of (a) have each voter submit an ordered lists of all entries, or (b) have each voter distribute 20 points across all entries, with at most 10 points per entry and voter.
It will be radically different, but it will speed up the process enormously, and you can look at any subset you like.
You can still hold a French presidential election between 2-3 winners of the list/score round.
