Scattergun - you continue to miss the point. It is that using the average only is too simplistic. You need to know the distributional shape of shots fired as it compares to various situations.
I can't give you that data because it doesn't exist in reliable form. The FBI shooting reviews, SOP, Wound Ballistic, etc. don't have that data. Their data is crude.
Then even if you had such, once again - folks need to decide on the basis of the extremes of the distribution and the probability of such.
That's the point, Sir.
When some one asks whether they should carry XY or Z because the average is some number, they, unfortunately, show their ignorance.
