They were at least 2-3 seconds apart, as you could interpret from the 2 differing screenies 200 was rolling quite slow that night. since the First screenie is about 4-5 seconds after the Second. But the observer position is a slight possibility, i had just shot down a Zeke i believe.
no idea other than that.
although i remember a while back where there was some wierd bugs, like the "G/S" icon. that dissapeared when you got close.
