You seem to assume that there’s a linear relationship between the intervention and the effect. This might be the case for cash transfers but it’s not the case for many other interventions.
If you give someone half of a betnet they are not 50% as much protected.
When it comes to medical treatments it might be that certain side effects only appear at a given dose and as a result you have to do your clinical trial for the dose that you actually want to put into the pill that you sell.

Hi Christian—agreed but my argument here is really for fewer treatment participants, not smaller treatment doses
