If I produce a gecko/snake/etc., thus knowing what produced said critter, I don't have a problem stating the het percentage of that critter. Same for selling something, that is het, and came from a trusted, and ethical, friend/breeder.
What is wrong is when someone states that an offspring is 50%, or 66%, het when neither parent is 100% het (and, of course, not of that morph) and have never produced something of that het (morph).
