I think you may have misunderstood my idea. I was thinking that candidates would choose to go into the HTC, not that they would be required to. (And when I said “things you really care about” by “you” I meant candidates, not examiners.) And I wasn’t assuming it would only work if you cannot leave the room before the 24 clock hours/12 subjective months—indeed, it would work better if you could decide to stay as little or as long as you want.
