I think that where Brad and I (and many other British trainers) maybe part company, is on the subject of "reward." I let my pups hunt, flush and chase every bird they can find until the point part of things is taught to the pups by the birds. To my pups just finding a bird is a reward in itself. I work pups only on wild birds, preferably partridge (English) or red grouse but I do use pheasants too when they are present.
I continue to hunt the pups and very gradually teach and encourage steadiness to flush, my dogs sit following the flush. Then I add the shot to the flush but before I do that I very thoroughly teach the pups that they must stop and sit if they hear a shot from close by as they hunt or move around. When the shot is added following a flush my pups already know they should be sitting, they have seen a flush and heard a shot …. that is two commands a pup has had to stop/sit and be steady.
I then add onto this a stop/sit to "fall." The object that falls is not a bird to begin with , it is a training dummy, or a ball or even a frisbee. I insist the pups stop dead in mid hunt whenever they see an object in the air fall to the ground. So.… now the pup "knows" three commands to sit that don't even need me to give vocal or visual or whistled commands. All of those three cues mean stop/sit to my pups.
I then put it all together and actually shoot a bird for the pup. So far not even one pup has ran-in if it has been taught in this way. I very often leave the pup in the sit position then walk out to the shot bird myself in the early stages of training. I then pick up the bird , which serves two purposes. It "claims" the bird as being mine and it leaves my scent on the bird which is what the pup would expect from a training dummy..... the bird is then treated by the pup as a retrieve and not something to be played with.
So … I very seldom reward a pup with a retrieve following a flush. My pups and my adult dogs are regularly hunted without me even carrying a gun. The point itself is the reward for my dogs. I think Brad and most other Americans differ from me in this … they make the retrieve the reward ….but , for the most part, they haven't paid enough attention to steadiness to shot and fall so run-ins result ???
Speaking both for myself and for many other British trainers of pointing dogs I can assure you that dogs become plenty keen on hunting and pointing even if no birds are shot for them at all. If you doubt this remember that no birds are shot over the dogs in our pointer/setter trials. The "reward" is the point, not the retrieve. The retrieve is a whole different ball game.
So there !

Sorry to have been so dogmatic ! :roll:
