Really well written mate. It amazes me what knowledge is available for no cost on this platform. Where you'd go to find a similarly interesting and considered writeup I dont know. I also like how dispassionate your article is; searching for signals in the data rather than relying on bias or emotion. Of course writing bots must rely on the former. Keep up the great work.
