I would like to interject a comment.
One area that I as chair have found we do have control over when it comes to the amount of time available for questions is the number of witnesses that sit at the end of the table. According to this, each presentation can take 10 minutes.
Mr. Dykstra, in the committee just before--a legislative committee--had, I believe, seven witnesses sitting at the end of the table. If each of the seven witnesses were to take their 10 minutes, that's 70 minutes gone out of a two-hour session and barely enough rounds for one speaker out of each party left. I would like to see our committee be a little more careful, if you will, in selecting witnesses so that we can at least question at length the witnesses who do show up here, without having just all presentations.
