Question:

When should a method be declared protected?

Answer:

It tells the users of your class that you do not want them to access those properties or methods and that they need to be careful when doing it.

outside of the unit where it is declared, a protected method is only accessible by derived classes.

you generally have to be careful about using such a method but that's not the main point of declaring it 'protected'.
