Hi,

Just want to mention that not all people agree on the
terminology used in [Ramakrishnan90a].  In [Ramakrishnan90a],
the authors used the term, "knee of the delay curve" to mean
what others would call the "knee of the throughput curve".

Others would argue that the "knee of a curve" is the part
that "bend the most" (i.e., smallest radius of curvature).
If you look at the delay curve, it bends the most at the
point that corresponds to the "cliff of the throughput curve".

  You are correct.  There are other slides that show the knee
  at the right place:
  
      slide 50 of lecture 12
      slide  4 of lecture 13
  
  Thanks for catching this one.
