The original 2009-2014 district points system was by FIM (i want to say Jim Zondag? Dont quote me on that though). With how 2015 worked though, a new (and our current) district points setup was needed, and was created with the help of all existing districts at the time, partly discussed in the linked blog:
There also was a whitepaper created for it, but despite using Wayback i have no way of finding that paper. (you’re free to try though, linked here.) I do have this Chief Delphi PDF file, I think from the 2015 Missouri State Championships(?) offseason event, that I think is the same paper, but I cannot verify. This whitepaper can be found here.
Edit: Looking at my rip of old FRCFIRST Robotics Competition documents, I think the the whitepaper I linked is the correct one discussed. You can find the one that was on the old FIRST website here, but they are the same paper.
