Just to fill in here. Hogan Torah wrote a piece a few years ago called AAAAAAA (https://hogantorah.medium.com/aaa-aaa-aaaaaa-aa-aaaaaa-aaaa-aa-aaa-aaaaa-1fec233a15b5 ) which James has credited at the bottom of his piece. Hogab also rehashed the piece a few weeks ago here. https://medium.com/the-mitch/aaaaaaaaaa-aa-aaaaaaaaa-cef5f2c9ed3d

Make sense: N-O
