I expected that result, Stratcomm, however it didn't occur in practice. Only doubling (usually, I triple or more to make them comparable with fighterguns) the vel still has the blobs missing bombs all over the place. And bombers too, even when they fly in a straight line. However, this could be a result of some accuracy setting I'm not aware of, like AI level or something.
Also, I noticed high-AI bombers jink automatically. That will render all but point-blank fire worthless, so we can speed the blobs up all we want!

Thinking about it, I think the blobs miss because the bombers are slightly adjusting their course to stay on target against moving ships, thus over the flight time of a blob they change angle enough to be missed. That's pretty lame: thats WWI-level AA fire.
