Larry,
That kind of misses the point of notation. If I could just have Bach show me how to play Invention #8, I would. I can't, so I do the best with the notational representation that he left us.
The same goes for most sheet music and chord charts that I've worked through over the years. I rarely have access to the composer to know what they intend.
I agree that if you do have access to the composer or are learning to play an arrangement the way someone else already plays it, then you are good to go. I do that, too. I also work a lot with musicians who don't know the names of the chords they are playing.
As I said in my first post, this is a pet peeve of mine and most folks don't care. You're clearly in the 'don't care' group.
