I've been waiting for Gary LaPook to say something, but haven't seen a reply from him or anyone else. A number of years ago he posted this material on the Bygrave method: http://fer3.com/arc/m2.aspx/Bygrave-slide-rule-LaPook-sep-2008-g6329 Instead of variable names y and Y, my Bygrave variant calls them W and X. Maybe it would have made more sense to name them X and Y so you could solve for X, Y, and Z in that order.
