That then raises the question: what is a unit of communication?

If communication is 20% verbal and 80% nonverbal, and if communication is very nonlinear in understanding (as with your book example), how do we know what 1% of communication is? What does it mean, and how can we tell that the figure is correct, when our main or only way of detecting whether communication succeeded is through understanding or lack thereof?

That's not even a good test, due to miscommunication. Both parties might think it succeeded, but then much later on you find out the truth (maybe).
