Speaking of dar bar, I've noticed that it doesn't seem to register in certain cases until I'm within a certain distance of an enemy plane. For example, if the Bish are hoarding a base I will often fly to the next base to interdict the reinforcements. However, the whole time I'm flying there, no dar bar is showing, only for me to arrive on scene, have the dar bar change, and then spot 3 cons well above the dar bar alt. In other words they were climbing out without dar bar showing until I got within a certain range of them. Is there any explanation for this phenomenon?
