My understanding is that motion 4 is not how we practised last time. Last year we actually handed out a chart that showed the speaking order. It showed what you described earlier, Mr. Chair. Rather than five minutes for each round to each party, it was to members of each party that had not yet spoken. That's the distinction.
So number 4, as printed, is not what we adopted as our practice for last year. We actually had a diagram, and we went to great pains at that time to show a diagram.
