                     Notes:
  
                     -  Only two of the above responses #4 and #7 contain
                        final results; they are indicated by
                        is_final: true. Concatenating these together
                        generates the full transcript: "to be or not to be
                        that is the question".
                     -  The others contain interim results. #3 and #6
                        contain two interim \`results`: the first portion
                        has a high stability and is less likely to change;
                        the second portion has a low stability and is very
                        likely to change. A UI designer might choose to
                        show only high stability results.
                     -  The specific stability and confidence values shown
                        above are only for illustrative purposes. Actual
                        values may vary.

                           (repeated) results.
