I suggest that we land on maybe six minutes, with discretion to the chair. Sometimes we have panels of three, for example, and if each one gets 10 minutes, obviously we really shorten the question rounds. Depending on the panel, depending on how many people and depending on other circumstances, I think you, Mr. Chair, may use your discretion as appropriate, and we'll give you that flexibility. However, let's say, as a baseline, six minutes.
It may be hard for us to impose a pre-written submission rule, just because sometimes we only reach out to our witnesses a day or two ahead of time. Maybe we could encourage witnesses to submit written documents but for the most part keep it as is, with the six minutes and some flexibility for others.
