....On a blind 2-3 feet downwind is a good spot to be ...
Continuing off topic for a moment if I may

Yes. If the dog were inside the corridor to the blind when it winded the bird, the fact that it had winded the bird would be a moot point to me......
But ,If the dog were outside the "corridor" to the blind, and in spite of the considerable efforts by the handler to the contrary (many casts); or, no effort by the handler by electing to let the dog wind the bird from well downwind , these facts would be reflected negatively in how the dog was scored ...

On a mark winding a bird from inside the AOF is a good thing in my estimation, and not to do so from the downwind side, if it happened repeatedly, could possibly call the dogs nose into question.

A wind save from a hunt outside the AOF would be an entirely different matter.
