Here's something Azedalis made me aware of. Just thought I'd share it with the group, as it were.
like most people, i always believed it when they said that bombers get an extra 10% stacking penalty that interceptors and fighter/bombers don't get.
I ran the test, just like Azedalis suggested. used interceptors on ground attack mission (a new experience in and by itself). suddenly they too have the extra 10% stacking penalty. (4 planes in the wing; stacking jumped from -30% to -40%)
even after all this time, you still learn something new here! don't you love that?
