Those film I posted, I usually hangin around 4-5k. 20 min over target area for 16 kills and a few assist so I am averaging a kill every 1-2 minutes. I usually average about 12 kills per BnZ mission, sometime I've stretch it up to 26 kills w/o rearming in the D9. However, I try to go home after 12 kills, even if I still got 250 cannon rounds and 50% fuel left.I don't see the point of flying at high alt, not when the fight is OTD most the time. I'm a pretty aggressive BnZmer, though I'd almost never take a pass at one guy twice. I have about 90% success on kill on the first pass, so I usually never have to engage him again. If I do miss him then I'd immediately look for a different target because I know the guy I just miss will most likely be tracking me.
When I bnz I'm an opportunist, meaning I will always search for target no matter what I am doing. At times I took out 3-4 guys in 1 pass, 2 on diving down, and 2 on zooming back up. Since when I bnz I'm usually look around because people always appear in front of me for some reason O.o. Half of my BnZ kills are just target that pops out infront of me that I didn't intend to kill them until they present them self near my gunsight or in my flight path some how. That's how SA can help out so much. Usually if I am BnZming then there are a lot of baddies within the area. So target environment will always be rich.
