An acronym coined by American Pat Steigman. It describes a method of describing a given throw. The five characteristics that can be controlled by the thrower are the angle with respect to the wind (W), the elevation of the throw (E), the amount of layover (L), the amount of spin (S) and the hardness of the throw (H). For example, a description of throwing a fast catch boomerang might be W:90° E:0° L:0° S:high H:high. An Accuracy throw might be W:60° E:10° L:20° S:low H:medium.
