My excuse is I was off thinking about some flatter mirrors I saw at the auto parts store when I started writing. Still on the line of thinking that steered me away from those.
I think your analysis is right. Maybe I should just say I was wrong.
EDIT: you could also do the Bondo-on-foam method instead of modeling clay.
