I really like this solution.  The reason I was procrastinating with
updating the PEP to reflect the previous solution was that I really did not
like the fact that it would make fold=1 times in the gap equal to the times
right before the gap.  Now this problem will go away with many others.

Let me sleep on this, but I really think this may work.
