As I said, I attended the 1st weekend course they did back in 2012, so not sure what it is now, but it was nothing like the Magpul video. Pete, the instructor, was a VERY legitimate BTDT guy who had no interest at all in selling anything. He never claimed or represented that Accuracy 1st had invented anything crazy or "new". The outlook was that they were just teaching the same science in a more approachable manner and that over the past several years from real-world engagements the Mil Sniper community had changed some ways they'd taught and done things prior to the war/s.
What I liked about the course, and Pete in particular, was that before they taught something, they tested it. Even if it was accepted gospel in the shooting community and things he'd taught for years in Mil sniper courses, they did the scientific testing on it. He (Pete) does a lot of work with DARPA, and they (Accuracy 1st) apparently maintain close contact with Brian Litz, comparing projections to range observations.
I completely get some of the opinions of the Magpul videos, and I'm certainly not arguing with Graham or trying to "defend" Accuracy 1st, I'm just saying that the class was very low-key with no sales pitches or gimmicks, and was a nice weekend of banging steel.
