I practice at 1, 7, 10, 25 and 100 meters with pistol.
I know of very few people who practice at one yard. This I believe is poor planning. You might think that you can't miss at that range but you can. You need to get used to the idea of shooting at something too close or you might hesitate at the wrong moment.
