I think it says something that out of old editions B/X is still so well-regarded among old-school fans for being simpler than AD&D. Sadly when I ran it for my players they found it too counter-intuitive. I consider it a personal failiure as a gm to properly represent the system, even though they assure me it was not my fault.
Yeah I wouldn't worry about it too honestly; it's very tough to get into OSR style games without having watched a session, played a game, or read a few OSR-y Internet thought pieces. Much of how it's done is cultural and not presented in the books. That is one of the things that later editions of D&D are better at.
