My opinion is this: at the end of the day, people's "personal standards" mean nothing.

The only thing that truly matters is how their dogs do in open competition

Quibbling over "what someone else does" on their own yard, with their own dogs, shows a serious mental imbalance IMO.
I can't change what you're going to do, and you can't change what I am going to do.

If a man's dogs are winning, then shut up.
If your dogs aren't winning, then shut up.

If a man's dogs are repeatedly and consistently winning in open competition, then that is all that needs to be said.
If your dogs are repeatedly and consistently winning in open competition, then that is all that needs to be said.

Worry about your own standards, and if you're able to meet and beat (or lose deeply game in a long haul with) the best in the sport, then you're on the right track
However, if your dogs are only heroes in your own backyard (or imagination), against nobodies, but you have never actually produced dogs that have faced/beaten (or lost DG to) truly great dogs, then maybe your "opinion" isn't all that it's cracked up to be, when put under the microscope of factual reality.

Now, if someone else's dogs are getting out there and winning consistently, AND yours are too, then maybe BOTH ways are effective ... and there might be "more than one way" to do things right

Producing dogs that can win consistently is NOT just about "testing individuals" in the box ... it's also about effectively managing key genetic traits in the brood pen
