Discussion Regarding Triangular Calibration

I need to make a correction about what I said earlier with allowing rotational radius to adjust. In reviewing the code, even though I allowed it to be adjusted, at the same time I set it back to the original value… oops… if I allow it to adjust, it drops down to ~133 in order to minimize the error to 0.0001. This is a bad thing to do in my opinion, so I calculated what I believe the real rotational radius should be for the ring kit (see this thread).
