You slide the performance bar until the calculated speed matches the measured speed, then it is calibrated. Once you get the performance bar in the right spot then the spine choices are accurate.
I do think AA is much easier to use and setup but I don't think one is necessarily better than the other. I have both and, when set up correctly, they both give me the same result.
