The other comment I was going to throw out to the committee is I don't have the experience that my colleagues across the table do, but I'm on a committee that's been going for two weeks now, and in that we're using five minutes consistently. Five minutes goes really quickly. It does really help you tighten your questions, though, so there's a certain value to that in helping move things along and really get to the point. When I saw six minutes, I thought, that's being really generous, and hadn't considered a seven-minute option.
