Funny, in spite of all the "data" you've provided to claim that AR's promote high grading that the very state you use for your example still has AR. They have simply inproved their method
You are correct that they still have ARs and after 12 years of ARs they still had high grading. Which proves even when biologists realize they made a mistake ,it takes a long time for them to correct it. Our ARs were based on Miss. computer models which were proved to be wrong. How long will it take the PGC to admit their mistake and correct it.
Remember that Kroll said he would still favor ARs even it did nothing to improve the herd . That shows the inherent bias of QDM supporters just as Miss shows the same bias..
