Hi Jameson,
 
Just passing through at the moment. I read this though and wanted to
comment.

I am finding myself looking at utility less because it doesn't appear
to me that any methods are very good at maximizing it, or differ all 
that much in this respect. In that case perhaps one would do better to
focus on something that methods do differ at, which seems to have a
clear value, instead of fighting for the last tiny scrap of utility in
the odd belief that simulated utility numbers will take anything else
of worth into account! Even if that's theoretically true, we're nowhere
near to possessing such numbers.

If BR means "shortfall from the best outcome that was possible" then I
want to note, that in 1D simulations, I find all of the Approval-ish
methods to be rather poor. But again, the difference is so small, it 
may not matter.

It is hard to gauge what one "unit of regret" means. In the sims I'm
looking at at the moment, the top method (of over 50) had 25% less
regret than Approval, which was the 3rd worst method. How can I tell if
25% is a lot, and something to be concerned about?

The two methods' rates of electing the utility maximizer were 89% to 
87%. Now it doesn't seem like that much of a difference, does it...?
