Any better is a subjective way to put this. 4 meq/L alk with 380 ppm Ca is not balanced in comparison to the ratio NSW. It means there is excess carbonate compared to calcium. When something becomes excess, it artificiality makes the other component limiting, when it is not limiting in that way in nature.
