I had that in my poll (it was called Lum’s Long Odds). It didn’t get a lot of love over there.
I like the idea, but it seemed like it a) promoted some odd behavior around forcing your opponent into good (for them) matchups to limit their point options, and b) it was a bit more of a process to manage, because it was a swiss format… That said, I like the idea, so I’d be up for trying to revamp it to address some of those flaws.
