I have enjoyed and learned a lot from reading Fred's books and attending his class at Black Widow. Fred, like every other good instructor I've ever met, believes that a good solid foundation is absolutely necessary before you can become accurate. Maybe even moreso than other instructors, in that he believes that you need to focus 100% of your attention on the mark you want to hit when you shoot instinctively. The only way you can do that is to have rock-solid form, which includes alignment, anchor, drawing, and followthrough, that you have honed to the point that you can forget it and focus on the mark you want to hit. If you're focusing on your anchor or whatever, it just means you haven't practiced enough that you have reached the point that you can forget it yet. Don't rush it, hone your form first and then work on accuracy or instinctive shooting. If you were to attend Fred's class, you would spend several days in front of a blank bale working on each element of your form until he was satisfied that you got it. He would lecture about instinctive shooting in the class, but aside from fun times in between sessions, there wouldn't be much hands-on practice of instinctive shooting in the class.
It can be discouraging to shoot regularly with compound sight shooters. We will never be as accurate as the good compound shooters, but that doesn't mean that we can't take game cleanly. It just means that we have to develop sufficient accuracy to get an arrow into the vitals at 15-20 yards, and then somehow manage to get that close to the animal we want to shoot.
I don't think anyone would disagree with Fred's discussion of the "instinctive" part of instinctive shooting. On the other hand, his body position is pretty unique, and many people who like to shoot instinctively will still choose to take a more conventional stance.
