I took away from the article that volume of rounds fired, in itself, doesn't a good shooter make. Doing the basics over and over to get the muscle memory, dealing with malfunctions, the reload, the draw, sight alignment and trigger control, should all be consistently and persistently done. As mentioned, the veteran LEO's were tired of the basics and wanted more. A human tendency to want to mature in what we do. Just a good article, I thought. Reminded me of the "only perfect practice makes perfect" thing.
Good stuff
