There is confusion on the side edge angles, guides and settings.
Basically the Europeans/International tool manufacturers use the acute angle from the base (needs to be flat) to the face of the side edge while North American manufacturers use the angle of the guide that creates the angle.
In the this example 2° side edge needs a Euro dedicated side edge tool of (or multi-tool set at) 88° or a NA dedicated side edge tool of (or multi-tool set at) 92°.
