Totally agree with the above points about hobby use. If that were the case I would just use the plate as-is and not worry about it.
But I have a small business designing and building tools/fixtures for a few clients. The cal and cert are still not an absolute requirement, but since I got the surface plate used, I'd like to know what I'm working with. After the initial calibration I'll probably never need to have it done again.
