Assuming that minimum reinforcing will provide adequate strength capacity for the section being designed, I have found that many masonry contractors prefer to deal with less vertical steel. For instance, if minimum reinforcing satisfies the strength criteria, I would use .0007bt for vertical and (.002-.0007)bt for horizontal. (Those vertical bars get in the way - ouch). Of course this approach depends on your specific condition. In some instances I have modeled retaining walls with lots of corners and the horizontal moments are larger than the vertical, requiring more horizontal steel (this really confuses contractors). than vertical. Also, it would seem to me that in the case of a wall (walls generally being longer than tall), there would be a tendancy to provide more temperature and shrinkage reinforcing.
