That is indeed the management style the PGC is currently using. Just because they don't use that name for it doesnt mean that's not the general management principle they're following. If you understood what thse terms meant you wouldnt be embarrasing yourself.
The quote I posted showed that prior to 1980 they were managing the herd based on the same general management principles they are using today. But, during the period of the quote the PGC was managing the herd at a RDD of 30 DPSM and now the same agency is managing 2 G at a RDD of less than 10 DPSM.
BTW, I just proved it is you that don't understand the terms. I have the report in front of me that lists the RDD definitions. Do you know how many RDD they list in that report and do you know what each RDD signifies?
