Well I was having trouble finding a combination of two discs to drop WIN 748 charge I was working with. After trying a few "almost there" settings, I got to wondering whether the adjustable charge bar could be stacked with a disc, and yes it can. Allowed me to get right where I needed to be. Not at home and cant remember if the charge bar was on top or bottom, I think it was bottom...it would only work one way.
