Same principle as B17s and B24s flying 300mph in this game, though, max speed drags every chase into a prolonged 6 chase, slowing the closure rate and leaving the attacker sitting there in the guns longer.
Sure, it'll be slow, but I just meant drag out the enemy's chase as long as possible. If you had a spit9 chasing you down wouldn't you want to pop him in the snout at 800-1000 yards? hehehe
