For one dogs usually produce the average of their line not themselves. So said hard-tested dog may in fact be a garbage producer, where as his untested sibling could possibly be a great producer.

The "Hard-Tested" moniker is to make the owner feel better about what they are feeding. When in actually a person should only be concern with thier own feeling towards an animal. Learn the line and learn the individual then learn some common sense.

One fact to always remember is an animal is only as game as his last showing. Deep game today may not be quite as game tomorrow.
