No one is perfect.....
We who write and approve these documents do so in an industry agreed format, and with appropriate quality and conformity checks along the way. It is with the intent of providing properly trained pilots and maintainers the information they need to assure that they can operate and maintain the aircraft safely, and the way it was approved.
If pilots or maintainers do things a different way, it's theirs to justify to whomever should inquire.... I'm not inquiring - I'm not in enforcement or warranty!
