The pictures aren't a very good indicator since they're 2 dimensional and lack relation to distance. I think I saw the picture being referred to and the individual kneeling with the AK is over 3 tables to the side of the revolver shooter.
I've also been puzzled by identifying who was in charge. I would usually check with everyone on the line before going downrange, but you can't keep your eye on everyone while you're setting up targets.
I also admit that everyone does a pretty good job with muzzle control and keeping their firearms cleared when not in use.
Put me down for the RSO class, too. One day would be easier than 2.
...and I'm not worried about you making a "profit" by doing the class. Since you run this website out of your own pocket, we know where any profits are going. [poke]
