I'm one of those folks who can't focus on my own thoughts during a presentation. I can understand the ideas being presented, but cannot critically evaluate them until later. All I can muster is to write down questions. It's just a bulleted list of "Slide number/title. Question." I can ask them in real time if the presenter consents to interruptions. Otherwise, I'll ponder over them later when I can focus, and follow up if necessary. I pretty much never approve any decision in a presentation without later analysis. That is, unless there is somebody else in the room that I can delegate that analysis to post-approval.
