Do you think your evaluation of good books vs. not-so-good books might be personal? In other words, the few books you found helpful, the 10% which conveyed 90% of the knowledge to you, might not be the same 10% which will speak to somebody else?
Most go books I read were Asian books with very little text. I do not read Asian languages, but the texts mostly were extended captions and contained short diagram number, move number or short variation sequence hints. (It is very easy to perceive such if only one can identify arabic / Asian numbers, latin / Asian letters denoting intersections and kanji saying "diagram" or "variation".) When I read books, I try to get as much from their contents as possible. So regardless of what the authors try to teach, I also parse, in each diagram, each move, each strategic line, each sequence, each group, each strategic choice, each positional judgement, each global relation, each strategic concept and each strategy I can perceive or verify by my own tactical reading.
There are limits to my perception because it is very hard to perceive new concepts that the book author does not teach explicitly, that no personal or public teacher (of those teachers I have seen or whose books I have read) anywhere has ever mentioned and that I missed completely thus far.
So although it is possible that a few readers might perceive a particularly well hidden concept faster than me, this is unlikely for most readers because otherwise I would have seen some of them mentioning those concepts some time. What every reader can get out of books must be similar to or less than what I can get out of books because, see above, I really try to be exhaustive. (There is, OC, the difference that Asian books teaching significant context in non-trivial text offer those readers significantly more than me that can understand the Asian text.)
So what I see in by far the most books is the same boring contents I see in most other books. I already felt lucky on discovering just one move in a book teaching me a new detail, a move that the author did not emphasise but that was merely part of a sequence meant to teach something else.
However, 10% (probably less) of the books are different: they teach important, essential concepts explicitly, concepts entirely neglected in the other 90% of the books.
So, no, I do not think that my assessment is too subjective.
(Instead, IMO, my description is an understatement. Go to Asian book shelves and notice the very many beginner / school books with even much less contents. I never read such; it would be a complete waste of time. Sort of books for the 40 kyu.)
2. About getting to be strong without reading books:
Do you have any data about all the strong asian amateurs/pros and how many books have they read?
No.
have been told the same by some of the very strong Asian players I have run into, mostly Japanese and Koreans - they say they had little use for books, never read them much, only for tsume-go and replaying pro games.
Of course. This is so because there are almost no theory books for very strong players. I have been stuck at my current playing level also because I have reached the end of "easy" learning by just reading suitable theory books. (Tsumego and pro games offer something for also the strongest players. So these I study and learn from because there is not the much more efficient study source books. However, discovering further hidden concepts equals doing research and so is very slow.)
