I think he has a good list, but it's kind of biased. Roberts book is rated ++ when he hasn't been able to read it himself as a player who doesn't understand those concepts. Another thing is books are rated bad because they don't show rank improvement. I think a lot of the books mentioned do improve your rank. Not your overall rank, but your strength in that specific subject. It's not that his list is bad. I think it's really good, but its incomplete.
