Another good way that I've seen battles made more even is to start the accuracy at 50%, then have it decrease by 3% per square. You then make your sensors twice as effective as ECM so that you can get a maximum to-hit of 99% at a range of 1 only if you have a 50% advantage in either sensors or aggressiveness. It works very well, and makes it so it's not so easy to get unhittable ships.
