How about this for inclusion/exclusion:

Each voter scores candidates between minus 100 percent and positive 100
percent.

The candidates' total scores (over all ballots) are tallied.

The list is sorted pairwise with priority swaps going to pairs with minimum
absolute difference in their scores.

The sorted list determines the finish order.
