I like the current ack settings albeit they can be lethal they are no where near as bad as the last starfighter deathblossom that they used to be. It used to be unlikely a single plane could deack a field. Now it is plausible. For the record, I got single hit PK from auto ack yesterday, from the very first tracer that came up from the field, so I feel your pain.
To the OP... keep looking for the data, some guys are just wrong. Had a guy try to tell me that the Jug N was a clipped wing version of the jug, and never cared to admit that he was wrong although he posts here daily like a sage on high. Stick to your guns, just find something more tangible then a first hand personal account.
