Ed Foote and Coleman 11

[Robert Scott]

John, I don't remember how I came to have my version of Coleman 11.
It might have been a personal e-mail from Jim Coleman Sr. or I might
have copied it from a posting on pianotech.  I guess only Jim Coleman Sr.
can resolve the difference and say which is the true Coleman 11.

In any case, the fact that the offset for A is not 0 cents should not
be a problem.  There is a good reason for not making A=0 cents in
Coleman 11.  If you do then the average pitch is much higher.  This
will make the piano less stable when changing from one temperament to
another.  In my version of the temperament, the average pitch change
from ET is much closer to zero than the one you attributed to Ed Foote.
But of course that does not explain the discrepency with the B.
