An alternative to the digital inclinometer is a bull's-eye bubble level mounted on the plate that supports the camera's fluid head. Choose a level that has an accuracy of 0.1 degrees. Use the 410's upper controls to center the bull's-eye and then look through the alignment scope to center the chosen star and you should be set up and polar aligned within a couple of minutes.

Are you making an assumption about the accuracy of the angle of the bend in the plate? You have several objects between the thing that you want to set, and the place where you are applying your measurement tool. If any of those things are not as accurate as you assume the errors will propagate.
