Thanks for putting up with me!
The excitment is in the simplicity of BTZS testing and in its precision. Regardless of what process you are using it is always good practice to make the best possible negative. And once you get beyond the initial learning curve BTZS testing is both easier, takes less time, and provides far more useful data than Zone system testing. So why spend more time to get less precise results?
