Just be tactful and feel it out I think... I emailed UArk to ask how many people I was sharing the finalist pool with, but I was really hoping it would result in a progress update. The head of the department that I was in contact with was also really friendly and had been enthusiastic about communicating, so I felt it would be okay. My communications with Tyler, on the other hand, have been kind of cold and I didn't get a response at all to my post-interview "thank you" email... So I probably wouldn't have felt comfortable asking for a status update from them. Thats my 2 cents
