What the hell are you talking about Zylon?
Picture this senario. You're fighting the shivans near a Ravana. The brief says that you must be less than 2000m away from it when a certain weapon goes off and preferably under 500m.
Using a status bar you've set up based on distance to the Ravana you could just look at the bar and you'd know instantly how far away you were from the ship at all times.
Using your suggestion on the other hand you'd get a training message the first time you went near the ship and then nothing. Even if you moved 10,000m away from the ship chasing after enemy fighters you'd get nothing!
That's why I said you'd need repeating message events. You need to take into account that the player will move out of range again after the first message has gone off.
Now the example with a Ravana is trivial because you could just target it but there are more complicated examples where a status bar could only be replaced by a lot of repeating SEXP's and even then it still wouldn't look as professional as a bar.
