I used to have an annual gathering at my place I had a big field back of my house about 10 acres. We dubbed it our annual balloon bust we would blow up about 60 to 70 balloons making them all different sizes.
Next we'd scatter them all around the field it went like this I'd pick some one to go first and he'd pick a balloon like saying the red one beside the green one. Then he'd shoot at it first if he missed it we'd all shoot at it one at a time until we all missed or someone hit it!
We'd walk up to retrieve our arrows and the person who hit it or came the closest to hitting it would choose the next shot and so on and so on.
Yardage was never mentioned or thought about some shots were real long and some ridiculously close. Of course it was a competition to see who busted the most. We all used judo points for safety and to prevent loss of arrows in the grass.
We always had a cookout also and it was a great time of food, fun, and good practice. We all also got rather good at lobbing arrows in at what had to be over 50 to 60 yards in some cases. You'd be surprised at how many people missed at under 5 yards or so also!
It was kind of like roving/stump shooting but easier on the arrows. I miss it, I moved far away from there and now live in the middle of a 12,000 acre WMA (Public Hunting Area). And I haven't been able to get anyone around here interested in a balloon bust.
This sort of shooting will really help, I don't like shooting for groups on a target for hunting practice. But I love making one shot really count, concentration is the game when it comes to instinctive shooting. I'm much better at making that one shot count than standing in one place trying to bust my arrows.
Sorry I know your question was for other methods of shooting than instinctive but I do not believe there is any better method for hunting with a stick bow.
