You can never rule out damage made by irresponsible owners (like hard training of obese dog during it's development).

Exactly, the systhem of A,B etc. was created apart from telling how severe the problem of the specific dog is to say something about his breeding worth (I am sure that is not the right English word but hope it is understandable). If a dog is A,B or C doesn´t matter for the dog, even the C is not likely to cause problems in a family dog but it is important if you look a pairings. When you can judge about this by DNA there is no need for this classification any longer.
If you look at some A dogs you will find that an A and even As over several generations don´t grant for A offspring. A very good example are the brothers Good Boy and Grey Wolf z Molu es, they are even out of one litter but the HD-results of their offspring are two different worlds (and some of the bad resulst seem to have been removed) and nobody can tell me this all results in stupid puppy-owners ore classification sythems, it´s bad luck in genetics. If we would have a test we could say in advance how the results of a pairing are likely to be.
