Rather than having three meetings, even if we have to extend the time for one of the meetings, I still think it might be better, to accommodate all the hours you're requesting, to have one three-hour meeting instead of having three meetings. I think it would be more efficient because it would leaves us a time slot to go back to our other study.
How do you guys feel about doing it that way: having a three-hour meeting, and then having a two-hour meeting?
