If lawyers had batting practice, what would it look like?

If only you could edit your questions.  Then each one would sound like it was right out of a movie script.  But you can't.  Once the words are transcribed, they are in final form, like it or not.  

Instead of editing, you have to prepare.  You need the equivalent of batting practice.  You have to make a habit of asking short, clear questions--questions that will elicit new information.  And you have to listen and follow up.  That means that your questioning needs to be spontaneous.  The way to make that happen is to practice so that you establish a groove, a default mode of instantly generating a question, without having to think about it.
