+	 | A failure has to be seen first so that when we hit a pass, we know
+	 | that it is truely the start of the window.  If we get passing values
+	 | to start off with, we don't know if we are at the start of the window
+	 |
+	 | The code assumes that a failure will always be found.
+	 | If a failure is not found, there is no easy way to get the middle
+	 | of the passing window.  I guess we can pretty much pick any value
+	 | but some values will be better than others.  Since the lowest speed
