David, my Duet has the ability to adjust the amount dispensed based upon the concentration level of the liquid itself (2x, 3x, ...) Then, the "hardness" or "softness" of the water. The machine further adjusts based upon cycle, load/garment weight, and soil level. Unfortunately that fine degree of dosage was eliminated with the current generation of WP/MT FLers. Based upon what I read as well as you pointing out, looks like the LG isn't as automatic, the user has to make adjustments particularly if the load size vary significantly from one to another.
