I noticed that they are slow to start engaging at all if automatic firing range is set to 75%. Moving it back to inherited (max range) seemed they would start engaging much sooner.
Also at 75% one unit will fire off a missile and then a oscillatory behavior starts on the other one where they will move in (towards prosecution) and out (to racetrack) of engagement behaviour without actually going near enough to the target to be allowed to fire until they bingo.
The behavior seems to improve as long as the prosecution zone extends into the area of racetrack patrol. But it comes add the downside of adding potential unintended targets.
