It doesn't change the rotor symmetry, the tool tells you if you have a good one or a dud. Moving the sensor board can slightly affect sensor alignment due to tolerances in the movement of the board.
Tuning for no load amp draw isn't a great method unless you already know what that particular motor performs well at. No load amp draw tells you nothing about loaded performance.
