Well hitech, I personally don't feel that the number of guns from one bomber firing on the same target is part of its preformance. However, I don't have the authority to make that call.
Let analyze again your totally naive statement.
Take the B17 as an example.
1. We model accurate muzzle velocities.
2. We model accurate bullet coefficients.
3. We model wind.
4. We model atmospheric density with altitude on the bullets.
5. We model the angles at which the guns can traverse.
6. On turret mounts we model traverse rates.
7. We model gravity accurately.
8. We model the dispersions do to gun mounts and barrel inaccuracies.
Now I choose not to model moronic gunners as you wish who would not all fire on the same plane when only one plane is attacking a formation. But if you wish I could adjust the gunners IQ to your level when you are flying a bomber, so most would just not fire when being attacked , because by golly it's just to hard for that 109 to kill us if we fight back.
