Pat Rogers had us using the 50/200 (which if IIRC is about 215) because from 25 to 250 or so it is a combat useful POA/POI overlap based on typically 5.56 trajectory. The offset for inside 25 yards was more or less compensated for by aiming at the hairline to hit in the eye socket. If you aim for the nose, POI tends to be about the lower jaw, which is sub-optimal, but aiming at the chin is likely to hit the throat. The neck is full of vitals.
