I again want to say that I resonate a lot with what you’re trying to do, since I’ve tried (and mostly failed) to do something similar myself before.
I worry a bit that you’re prematurely optimising approach-wise when you conclude the thing to focus on is figuring out the cost-effectiveness upper limit at which you can tell people honestly and confidently that their donation is doing that much good, instead of asking donors how they think about giving (which you did). For instance, Sawyer’s comment reiterates the sentiment I mentioned earlier that
Most potential donors are not really risk neutral, and would rather spend $5,001 to definitely save one life than $5,000 to have a 10% chance of saving 10 lives. Risk neutrality is a totally defensible position, but so is non-neutrality. It’s good to have the option of paying a “premium” for a higher confidence (but lower risk-neutral EV).
Orthogonally, I think most people are willing to pay more for a more legible/direct theory of impact.
“I give $2800, this kid has lifesaving heart surgery” is certainly more legible and direct than a GiveWell-type charity. In the former case, the donor doesn’t have to trust GiveWell’s methodologies, data gathering abilities, and freedom from bias.
and these aren’t necessarily obvious in advance, so if you start from a (simplistic) model of giving advisory effectiveness as being [number of prospective donors in your circle] x [fraction of donors who find argument X persuasive] x [$ per donor] x [expected good per $], then starting with an argument that works on yourself (and on me too — I don’t think we’re that representative of the donor pool) doesn’t let you get empirical input on the 2nd term, while asking donors does.

and Jason’s comment seems relevant as well:
