Dear Jim.
I have learned to do the test as you described above, everything is =
clear as clear can be
and yet, the tone improves!!!!

To all! Please try for yourself, I think that is the definite proof.
Just consider this: my teacher at the time in Japan was  the famous =
Tsuji-San (they call him over
there "the great one"), he did not have the answer!
And of course I have gone into this deeply myself but have given up =
untill I was able to put my questions before you  Cyber List Scribers!
I am sure we'll find it..
