Still I don’t understand why the offset is +1 at the start of chapter 0 and +2 at the end of chapter 0… Therefore, here are the pages as numbered by Bookwalker; maybe somebody can solve this puzzle?
Pages 1 to 7 off of Bookwalker
Pages 2+3: (page 2 is on the right, of course ^^)
According to the table of contents, Bookwalker’s page 6 is the real page 5, I think? So why is there an offset of 1 at the start of the chapter but an offset of 2 at the end?
