Wiley,
That is all very interesting. Thank you for your extensive knowledge. You are right regarding the intonation of the guitar. It has to be correct if one has any prayer of playing in tune up and down the neck. Outside forces coupled with the imperfection of equal temperament make the job of striking a tuning balance very challenging. Humidity, temperature, capo/finger pressure, saddle compensation, and more, all play a part.
That being said, I offered the above information only as a help in finding a way to tune ones' guitar without having to worry too much about all that other stuff. I've been there and have gotten tired of spending so much time tuning instead of playing. That's why I sold my acoustic piano and bought an electronic piano. Thanks for your input I appreciate it.

P.S. I have a Peterson clip on strobe tuner and find it's OK but it is so damn hard to use.
