This is exactly the sort of thing I'm interested to find, thanks very much for pointing it out! I'll pick up a copy of weighing lives next week.

I posted my idea for a normative rule, and indeed it is similar, though it seems to work in reverse. I'm also seeing issues with what I imagine Dasgupta's idea to be that my strategy doesn't have, but I can't say more till I get a chance to read the arguments and counterarguments.
