I know a lot of effort was historically involved in calculating how many hit of a certain caliber shell, it took to take out a specific aircraft, and how many of each shells fired would result in a hit.
     Loose example.  "it might take 20 hits from 20mm to take down a B17, but it takes 2000 rounds to land those 20 hits"
     Can we figure this out in AH?  In terms of our game?
