I think we both agree that bednets give a 17% reduction in mortality. The question is what mortality rate to apply this 17% to.
GiveWell say 11.9.
I say 7.7.
Based on your points I thought you were either saying (a) 7.7, agreeing with me, (b) an adjusted version of 7.7, which I calculate to be 7.66. Either way we’re agreeing here.
