I think you inevitably need to answer “What is the marginal impact of funding?” if you are deciding how much to fund something.
(I will probably write about approaches to randomizing to be maximally efficient with research time at some point in the future. My current plan is something like: write out public goods I know of that I benefit from, then sample one of them to research and fund by 1/p(chosen) more than I normally would.)
This isn’t really meant to be a quick rule of thumb, it’s meant to be a way to answer the question at all.
