This world is absolutely nuts.
If my pass score for a test is 75% I fail if I score 74%.
Not only would I be axpected to read a few more pages which -in theory- should give me the required 75%; I would be forced to redo said test!
So tell why it is more important to score a theoretical test within limits then to have a structure of an aircraft keep it up to the limits?

Explain that one to the "Daily Mail" after the first failure of a wing with pax on board..
