The problem you encountered is caused by the harmonic structure of any note. THe SAT is listening to a partial an octave and a fifth above the note being played. If you consider the closeness of the partials in that range you cn see how easily tuning to a different partial of the note can occur. The lower you are the more likely this will occur as well. THe aural testing you did is the exact and proper procedure of using the SAT when tuning an unfamiliar piano. If in doubt, listen. Newton nhunt@jagat.com
