The trouble with exact balance is that play in the RA gearing means it alternates between pushing, coasting and pulling. While coasting the motors have no control over the pointing. You can't completely remove all play because differential expansion would cause binding in cold weather and too loose in hot weather. Keeping it east heavy means it is always pushing.
