Dan that is the same exact way I practice with my recurve. To me its the only way to practice, at least for me anyway. I as well am anal as you are being if I don't hit my quarter on the target I think why I didn't. Most of my practicing is being done at 10 to 15 yards doing the quarter thing, 95% of the time I'll hit that spot If I'm concentrating enough and doing everything correctly. If not I'm upset with myself, I set my standards very high while practicing with my recurve at closer ranges. At 20 yards I'm no where close to hitting a quarter, I'm lucky at times if I'm within 2 to 3 inches if not farther off. Most of my kills with my recurve are at that 12 to 13 yards. A few have been in that 17 to 21 yards but not many. I've never missed or wounded an animal at 17 to 21 yards but its just not in my comfort zone as a 12 to 13 yard shot is.
