Nothing major, it's just the number or Marble Arches needed for the Atunement structure is wrong, it should be 88 and not 80. With the pictures it's not always clear exactly how to build the structures so the wrong info may cause people problems.

The data there is pulled directly from the structure matching data. It is exact and not manually added to the book page. Inconsistency there seems rather unlikely to put it lightly.

Double checked ingame, it is 80. not 88. and it also displays 80.
