I understand what, and why you ask for what you are asking, but just for example, a 40 bomb load out in a 29 @ a delay of .05 is 2 seconds. I'm not sure in real life it could have been done much faster than that. Seems I recall that in most bombers, the bombs were stacked vertical, so there would have been no way all the bombs could have left the plane at the same moment.
Now if there were a way to make your drones follow nose to tail and drop at the same location as the lead plane, that may get you more what your looking for and trying to do.

ps. yea I could be wrong too..... If so, sorry.
