But in removing one hierarchy, the time limit introduces another. A time limit assumes that all people have relatively equal access to time through their speech, which is not true. Stuttering is very unpredictable. I can rehearse something as many times as I want, but I don't actually know how long it will take to say anything until I have to say it.
And I understood intuitively that the purpose of this time limit was to create as non-hierarchical a space as possible.
