I ran some quick time estimates while watching a few contestants. I would estimate that between Ava taking an inordinate and seemingly random amount of time to announce if the answer is correct and the even more random transport to the next question she wastes up to 40% of the contestants time where they literally can't do anything. And that doesn't include the time it takes her to ask the question. It also succeeds in wasting the talents of Rob Lowe as he does pretty much nothing. Oh and one more thing it wastes, the time of anyone who watches this gimmicky mess.
