It would be up to the members of the subcommittee and how many witnesses they submit to me. Typically, I would take that list of witnesses, create a master list, and work with the analysts to divide them into panels based on their expertise and who goes well together. At that time, we would see; if there were three or four witnesses per panel, I would adjust accordingly and tell them they have six or 10 minutes for an opening statement.
All of that is to say that if the witnesses came to me faster, then I would know faster.
