Richard,

Exactly! How did it sound then? The only test that is worth its beans in 
sound is, the sound itself. however, from the original condition of the piano 
I doubt that any test would be in the ball park. In order for the duplex 
scale tuning procedure to have an effect, the piano must be, ( in my 
experience ) up to pitch and stable. Otherwise there are too many variables 
to makean appraisal of the value of tuning the duplex scale, in my opinion.
