I don't think it just applies to shotgun courses.
If you have a short target first and a long target second, if they are exposed to the same wind to the same degree then the aimpoint that works for the first will work for the second. Ie if the first takes 2 mildots, so will the second. Indeed if you could get it 1000yds it would take 2 mildots in the same conditions.
If you outlaw it, it's the same for everyone, which just means follow through will be more important than string pulling. No grumble from me there, it's probably one of the most overlooked parts of the shooting process in H/FT.
