Thank both of you for responding...

I intend to do what's fair because that's what you do. But I wouldn't want to be taken advantage of. I believe lawyers say there must be "real consent" and something else about consideration.

Anyway, Jill I bought some little elliptical stickers to put TCR values and the "n" number on each chip. That will only be for mutual reference and I'm not bound by it.

As in your Bucky's example, a 1955 double strike US dime is only part of a phone call for some, but 100's of dollars to others.
