That is where your logic breaks down and my initial post comes to fruition.
I'm preparing to defend my base from aprox.15 incoming cons.
My radar tells me there are 10 cons at 10k and 5 cons at 15k.
I can now dispatch 4 or 5 guys up to 15k to deal with the high boiz and the rest can stay lower to defend against the rest.
And if the higher cons decide they don't wanna fight against co-alt planes and run away--great!!
Maybe some guys will have to up from a nearby base, maybe not. Either way, the altitude info can be very usefull.
If I see a single con coming in at 25k, I probably won't bother upping from that base, or I may elect to up from a nearby base to intercept.
Logical?
