So at https://www.reddit.com/r/OnePieceTC/comments/4lq9nj/young_vivi_koza_who_drops_what_sengoku_books/ there are two things mentioned that I thought were not true:


 * that drops are pre-determined, so there's no need to attack desired target (ex. Elder turtle) first


 * that manual drops are tied to particular characters

Also those two are not compatible, I think. What's your take on that? IF only certain characters drop certain manuals, this would be a very useful bit of info to track and to add to the guides.
