I understand, sort of, but, I still need to understand. If a derived
property is derived, if one do not have interoperable results when
calculating it again from the origins, then there is a bug somewhere.
I have not seen anything that say what is normative if the calculation
is giving a different result than what is in the DerivedProperties.txt
file.
Do you have such rules?
