Dana,
There’s no reason to have stage fright. 😉
BB is uncomplicated, but powerful; and probably what is happening is that as you learn more about it, you’re beginning to see some of that power.

I may know some of the answers off the top of my head, but you’re paying BB for their expertise.
You might as well use it.
