The paper isn't intended to be a manual for how to practically compare agents. It will indirectly help there, I hope, by making people realize that they're looking at an election problem, and that there's a big existing literature on that subject. So in the practical case, say you have 10 different benchmarks, and some agents perform better at some of them, and others perform better at others. You could approach the problem from scratch, but it would be helpful for you to realize "oh this is an election with 10 voters and people have been studying how to decide elections for hundreds of years, I probably shouldn't reinvent the wheel". For example, it might take you many ages to essentially rediscover the Condorcet paradox and you might put inordinate effort into futilely trying to "solve" that paradox. Or you could stand on the shoulders of giants and avoid all that! https://en.wikipedia.org/wiki/Condorcet_paradox
