Here is the link to the PGC's "Fall Deer Chronicles"

The PGC is basically admitting that ARs protect buck that are inferior for the rate of antler development. Therefore, the average buck saved by ARs will have a smaller rack at 2.5 than the average buck carried over before ARs. That explains why the PGC has failed to release any data on the size of the buck harvested since ARs were implemented.
