The proposed approach of using a Condorcet method to pick one of all possible candidate sets is however quite heavy computationally. For that reason the number of candidates (and representatives) in each district should be kept quite small.

With three or four representatives per district, the computation is not really all that expensive. For example, with four seats and 10 candidates, there are 210 possible sets of winners. Running the Schulze Method on 210 candidates is not as expensive as you might think. The average home PC can compute the winner from the pairwise results in a minute.

10 representatives per district is getting a little ridiculous. It's not necessary or desirable for every fringe movement and special interest group to have its own representative in the legislature.  Plus, if there are 10 seats, there are likely to be 15, 20, or more candidates, and the voters can't realistically know and rank them.

Three or four per district would, I believe, suffice to broadly cover the political landscape and give the vast majority of voters a reasonable choice of representative.
