My measurement method is slightly different from the industrial standards.
The main reason is that my measuring instruments are not as accurate as professional ones. By and large, the measurements here on this website are less accurate than those of audio manufacturers.
My purpose of measurement is confirming normal operation of my works and searching for defects and shortcomings in my works. I don't intend to compare my measurements with those of commercial products or works of other audiophiles. Please be aware of this.
Meanwhile, as for the data I place importance on, I've set the measurement conditions stricter than the industrial standards. For such data, measured data of a manufacturer's amplifier are sometimes worse than those on its catalog, when the measurement is made according to Tonochi Method.
