Chamfer Not Obeying Tolerances

What I uploaded was a actual part of a machine, truncated. Regardless of what the dimension tool reads, it still reads better for the rotated VS the chamfered edge. I realize while it’s perfect because it is can’t be totally round, we still need tools to call out these type of dimensions to communicate our ideas for manufacture. We also need tools to make sure what we make is in good shape, or do we create something that can no longer measured?

I am disappointed in the chamfer tool, and perhaps also the dimensioning tool.
