The chance of an individual being hit by automatic fire is fairly low.

As much as i remember the spread area is not very big at those distances.
I got to shoot this gun occasionally at rusty vehicles at the range-that's my experience with this gun.

I was thinking about effectiveness when one gets the correct aim not about the difficulty in doing so in fast airplane which was tricky under combat conditions.
So obviously the more guns you have correctly aimed at this split second the more lead gets to the target.

To my knowledge having the guns in the nose made it easier to put most bullets in a target without worrying about the range vs focus point therefore it sort of compensated sometimes.
With the cannon one or two hits could be enough.
It probably also made for more stable platform than wing under load.
