I am also interested in the accuracy of the angle plate. Any good measuring tool must have a stated accuracy. And Gary mentioned Starrett, so I tried to look up the accuracy of their protractors. For their 490/491 series protractors, which most woodworkers might use, Starrett does not state an accuracy! At least it wasn't in the catalog. For their vernier-style protractors, the accuracy is better than 1/12 degree.
Guess I will wait to see about the angle plate
