Good point, thanks for flagging! Here’s what the function looks like to me (sheet):
Note that the X-axis is in terms of the fraction of the donor’s contribution actually going to the effective charity, and not in terms of the percentages displayed in the tool. For example, when you set the tool to “10%” and put in $1000 it tells you $105 will go to the effective charity and $945 will go to the regular charity. That means $55 of the donor’s initial $1000 is going to the effective charity, for a rate of 5.5%, and that is the value I use on the x-axis.
(Part of why I missed this is that the screenshot Aidan provided happens to show the only case where FarmKind and GivingMultiplier function identically)
