Brings up the point. When I try cutting a circle (small table top), I always plan on going slightly large since the multiple depth passes can leave "step tracks" in the edge. Rout large, then rout a single, full depth cleanup pass.
Using the saw for the primary cut would be faster and less dust.

BTW LBD, I bet you can find that "missing dust" from your trim router jig all piled up in your dust collector. Object permanence lesson ðŸ¤
