Very interesting...
I would like to add a couple of thoughts. All of these new fangled figures, numbers etc. describe the information available on these cattle. They don't describe which ones to pick.
Genetics is the business of selecting useful genes to pass on. Limiting selection to your own herd works pretty well if you have all the genes you need to do what you want to do.
If there are 100,000 cowboys in this country then there are probably 100,000 different ways to do it, and probably every cowboy thinks 99,999 of them are wrong.
Home raised bulls can bring genetics into a herd that are "pre-adapted" through the cows genetics. This is a slower way to change than to bring in an outside bull directly, but may suit a cowboys purpose.
