With respect to Fulton County Superior Court Judge Scott McAfee, I don't think he has made ANY questionable calls, rather he has presented a completely calm and competent demeanor and manner. His rulings to date have been well considered, explained fully and have "favored" neither prosecution nor defense.
What questionable calls? I saw growing impatience from the judge toward the redundant questions from the defense attorneys and several 'move on' instructions from the judge to those lawyers.
