I've got to totally disagree with you LHR16.
In the twenty+ years I've been in the industry, including as a weight & balance trainer, it's one of the best. The WAB's, BAB's & Codeco's are dinasours now and EDS have got a good product to move with the times. Why complicate systems with non sensical entries when you can have a clear and understandable view of your load & trim?
As far as advanced goes, this is probably the most advanced and comprehensive system of the modern era available. There are also plenty of options for adjustment!
