That's like trying to say that people who slow below the posted speed
limit for corners on a mountain road and go a bit faster on the
straights are trying to "out engineer" the people who designed the
road.

If you think doing things precisely according to book and never
exercising any judgement will keep you safe you are likely to find
yourself in big trouble. Judgement is properly exercised in BOTH
directions -- knowing when you need to modify the book numbers
downward is no more and no less valid than knowing when and why you
can modify them upwards. Think!

I don't know what part of the world you live in but I know one FAA
Operations Inspector who has a bathroom scale in his car. *I know he
has zero tolerance for violations of POH limits like gross weight and
seat limits.

I don't doubt it. There are brainless Jobsworths everywhere.
