Ha! That conversation and thinking is very enlightening to me. It's really making me think about the subject in ways I hadn't before.

Under n^2 those who hold the most SP under 1 account are the one who are advantaged as opposed to the current system where anyone engaging in 100% self-upvoting are the one advantaged.

I think that's pretty much what it comes down to. At the same time I'm not totally satisfied with my analysis. I feel like there's still something I might be missing but I'm not sure.
