When shooting at the range we all tend to shoot for tight groups. In a training I had a few years ago, we were taught NOT to shoot an agressor using a tight pattern. The thinking is that if you hit em twice in the same place your not going to make him bleed out any faster. Also, his nerve's in that area are already maxed out so hit him somwhere else and do some more damage. It makes sense to me. Just something else to consider if you ever need to shoot in a real life situation.
