I’m mainly just curious how such things work but I picked on data from a Go Fund Me campaign that I know people might be morbidly curious about.
The site gives a list of donations made with the amount and how many days ago the donation was made. Doing some minor spreadsheet wrangling, it is fairly easy to turn this into graphable data. The only departure from literal truth is I used the order in which the donations are listed to spread out the data points more evenly across each day of the campaign – so the smooth growth within each day is just to make the graph easier on the eye (the raw data would just give a big vertical chunk of points).
Compared with the fundraising goal the graph looks like this:
If we assume a growth rate of $20 every three days than this campaign should reach its target in about 1317 days or about three and a half years. Of course, events may change that.
