Faith, I'm on a quest.

I haven't seen my McFerrin for some time. I either loaned it out and forgot
who has it, or I've lost it somewhere in the piles, er, archives
surrounding my desk area. 

So here's the quest. If anyone out there has an inharmonicity formula that
is set up for actual use by relatively normal humans in a spreadsheet or
such, rather than in blackboard form in mathematical notation where it
impresses the scholars, but it's necessary to hire interpreters and
individually chase down all the referenced (but never actually included)
constants and such before it actually becomes useful... please send me a
copy of the formula. If you know the source, I'd like to know that too. I
want to set up as many versions as I can get into a scaling spreadsheet and
compare them head to head without making it my life's work. I'll then post
the compilation of everything I receive so some other random soul will be
able to get the information simply by asking anyone currently subscribed to
the List, because you will all save a copy to help out the next guy...
right? If I can get READY-TO-USE formulae, with the variables defined, this
should only be an evening's project for me and a lot of people can
potentially  benefit. Post me privately, or to the List where someone else
can play too, as you wish.

Thanks,
